For example, as a representative use of EEPROM, there is an IC card. Moreover, since it is convenient to rewrite at any time for visual use, the mask read-only memory (Mask R〇M) in the computer is replaced with EEpR〇M or flash memory. Further, in recent years, a system L SI or a buried type of so-called logical mixed memory in which a nonvolatile semiconductor memory is loaded into one of the logic 1C is required. Further, the analog circuit is incorporated as an adjustment switch for adjusting the analog circuit of high precision, and a small-scale nonvolatile semiconductor memory of several tens of thousands to several K bits is also required.

In the case of one wafer, there are problems in that the number of processes is large, the yield is also lowered, and the price (cost) of the product is increased. As a means for solving this problem, an EEPROM using one layer of polysilicon 4 201001420 has been disclosed (Patent Document 1).

Figure 2 shows the equivalent circuit of the coupling system of the non-volatile semiconductor memory device shown in Figure 1 a to Figure 1c. It is assumed that the floating gate FG has a charge q, and since the overall charge amount of the system is Q, it becomes (Vsub - VFG) * C(FB) + (VD - VFG) * C(FD)

Since the source is extremely open, the depletion layer diffuses to the channel CH portion of the transistor due to the floating gate FG and the substrate SUB. The capacitance becomes very small, so after ignoring, the floating gate potential VFG (Erase) is set to ΔVFG=0, then 15 201001420 VFG{Erase) = 0.1 x FZ) = 0.1 x 8(K) = 0.8( K) · (Expression 2) After applying a voltage to the drain D, as shown in Fig. 4A, first, the electric field concentration of the depletion layer is generated near the drain D, and the so-called high-energy Band to Band (B to B) flows. The current produces pairs of holes and electrons. The hole with high energy (hot carrier) is loaded into a part of the floating gate FG. After the voltage is further increased, when the oxide film is relatively thick, the junction collapses before the flow current of the FN (Fauler · Nordheim). Current flows to the substrate SUB. Let this breakdown voltage be VBD. In addition, for the details of the band-to-band (B to B) current, refer to "Documentation: "Flash Memory Technology Manual", edited by: Sakaoka Fujio, Publisher: Science Forum, Inc., 1 993 August 1st, 5th, 1st edition, 1st brush release. Chapter 5, Section 2, Analysis of the inter-band tunneling phenomenon of non-volatile memory cells, P206~215". Further, in Fig. 4A, the horizontal axis represents the drain potential VD, and the vertical axis represents the drain current ID, and the floating gate potential VFG is used as a parameter to schematically indicate the change in the drain current ID when the drain potential VD is changed. Here, since B to B and the collapse are generated at a certain electric field, they are dependent on the potential of the floating gate FG. As shown in Fig. 4A, the VBD also becomes low when the VFG is low, and the VBD also becomes high when the VFG is high. Explain the erase of the charge accumulated in the floating gate. At the potential difference between the gate and the drain, the critical potential for generating B to B is 5V. At VD = 8V, the floating gate potential VFG is implanted and erased before it becomes 3V. In other words, the erased hot carrier is injected. Since the initial VFG is 0.8V, 16 201001420 is 3V after erasing, so the amount of change ΔVFG(E) during erasing becomes +2.2V. On the other hand, the write system is VD = 5V and VS = 0V. At this time, the state before writing is usually the erased state, and there is a hole in the floating gate FG. Since the transistor is in an on state, the channel operates in a saturated region. Therefore, assuming that the channel area is about half, the floating gate potential VFG (Program) at the time of writing becomes VFG (¥r ogram) = 0.1 x FZ) + 0.8 χ ΡΊ) x 0.5 (Expression 3) according to (Formula 1). 0.1 x 5(V)+ 0.8 x 5(F)x 0.5 = 2.5(F) "- Generates hot electrons for writing. Here, since the threshold of the transistor is 0.5 V, the potential VFG of the floating gate FG becomes 0.5 V, and the current does not flow any more, and the writing is terminated. At this time, since the gate voltage is changed from 2.5 V to 0.5 V, the amount of change ΔVFG (P) at the time of writing becomes -2.0 V. Referring to Fig. 3, the transistor characteristics of this erase and write state will be described. In this figure, the horizontal axis is the floating gate potential VFG, and the vertical axis is the current ID of the drain D. In the three states of erasing, neutral, and writing, the gate current when the floating gate potential VFG is changed is schematically indicated. A chart of changes in ID. Next, a description of the reading is performed. The reading system is set to VD=1V and VS=0V. At this time, the floating gate FG has a charge of ΔVFG, and the floating gate potential VFG (Read) at the time of reading becomes

The operation of the memory unit 2〇〇 will be described with reference to Fig. 5B. The write operation, the erase operation, and the read operation are sequentially shown in FIG. 5B. During the write operation, the input terminal data line DL of the word line WL and the activated signal set respectively enters the potential of 2V. 'The data line inverts the signal line b and inputs the potential of ον. 'Data line DL, data line inversion The potential of the signal line is transmitted to the signal line and the line line Bit through the transfer transistor 1G6 & 1G7, and the potential of the signal line BitB is 〇v. - After the potential of B 8 V is applied to the control terminal s and the control signal terminal a, the non-volatile semiconductor memory device 2 〇i 20 201001420 becomes the write state 'non-volatile semiconductor memory device 202 becomes smeared In addition to the dissimilarity, electrons are injected into the floating gate of the non-volatile semiconductor memory device 2, and the floating gate of the non-volatile semiconductor memory device 202 is injected into the gate. On the other hand, in the erasing operation, conversely, a potential of 0 V is applied to the data line DL. After the potential of the data line inversion signal line is given 2 V, the potential of the signal line Bit becomes 透过 through the transfer transistors 106 and 107. v, the potential of the signal line BitB becomes iv. At this time, after the potentials of S = 8V and SB = 5V are applied to the control signal terminal S and the control signal terminal SB, the nonvolatile semiconductor memory device 2〇1 becomes the erased state, and the nonvolatile semiconductor memory device 202 becomes Write status. The reading operation of the data set in the memory unit 2〇〇 will be described with reference to Fig. 6 . Fig. 6 is a timing chart showing the reading operation of the memory unit 2A. 6 shows, in chronological order, the voltage changes of the respective signal lines of the input terminal of the activated signal set, the word το line WL, the signal line Bit, the BitB, the data line DL, and the data line inversion signal line D L B . The case where the memory unit 200 performs writing, that is, the case of reading "〇,, data. First, the voltage of the data line DL and the data line inversion signal line DLB is precharged to 2V (precharge). The terminal voltage of the input terminal of the control signal terminal S and the control signal terminal SB is set to S = SB = 〇V. Since the time t1, the terminal voltage of the input terminal of the activation signal SET is gradually changed from 2V to 〇v. The potential of the activation signal set 21 201001420 gradually changes from 0V to 0V. Thereby, the SRAM unit 100 is activated, and the signal lines Bit and BitB are charged. The voltages of the signal lines Bit and BitB gradually become south. When the "〇" data is written, the non-volatile semiconductor 5 memory element 210 is turned off, and the non-volatile semiconductor memory element 202 is turned on. Thus, the potential of the signal line Bit drops to "L ( On the low side, the potential of the signal line BitB is charged, the signal line Bit is set to "0", and the B signal line BitB is set to "丨" (time t12). When the voltage of the word line WL is set to 2 V at time t13, the transfer transistors 106 and 07 are turned on, the voltage of the data line DL becomes, and the voltage of the data line inversion signal line DLB becomes 2V, and the reading ends. Take action. When the memory unit 200 has been erased, that is, when the "丨" data is read, the signal indicating each state becomes the opposite action, and the voltage of the signal line Bit is 2V. The voltage of the signal line BitB is 〇v, the data line The voltage is 2v, and the voltage of the data line inversion signal line DLB becomes 〇v, and the reading operation is ended. The terminal voltage of the input terminal of the activation signal SET starts from "η" to "L" to the voltage of the data line D1 and the data line inversion signal line dlb, that is, the period from time t1 to U3 is the sensing period.疋 The advantage of this configuration is that the composition can be made simple. Further, the portion to which the high voltage is applied is a part of the signal terminal S and the control signal terminal SB connected to the nonvolatile semiconductor device 2, 1, 2, and SRAM # 100 (sensing portion).

The SRAM unit 100 (sensing unit) shown in the first embodiment is the same, but in the memory unit 200' non-volatile semiconductor memory device 2 (i-non-volatile semiconductor memory device) and 202 (second non- The source of the volatile semiconductor memory device is separated from the control signal terminal SB, but in the memory portion 200a of the present embodiment, the sources of the non-volatile semiconductor memory devices 201 and 202 are respectively connected to When the common control signal terminal S ° is set to be in common, the control signal terminal voltage VS for simultaneously establishing the write operation and the erase operation needs to be optimized. Figs. 7B and 7C show an example of changing the applied voltage of the control signal terminal voltage vs. Fig. 7B shows a case where the voltage of the control signal terminal is 7V. The cancer is recognized again (Formula 2), (Formula 3), (Formula 4-1), and (Formula 4-2). Here, since the pole is interchanged with the source, VS replaces VD. 23 201001420 becomes the initial state of the floating gate FG at the time of erasing, according to (Formula 2) = 〇_ 1 X 7 (" = 0· 7 (4) The final state of the floating gate FG is +1 due to becoming 7V-5V=2V · 3Υ. Therefore, the amount of change becomes the initial state of the floating gate FG when it is changed, according to (Formula 3) VFG(?rogram) = 0.1 x 7(F) + 0.8 x 7(F) x 0.5 = 3.5 ^^ The final state is erased at FG=2V, so the amount is +1.5V when FG=2v is set. According to (Formula 4-1}, according to (Equation 4-2), therefore, the floating gate FG is read. The initial state becomes FFG("0")=0.1 x 1(F) -1.5(F)=-1.4(F) and the initial state of the floating gate FG of 'reading '1' becomes = 〇·1X) + 〇·8 x 宁)χ 5 +1 3(F) = 1 ·8(κ) Therefore, as the threshold value of the non-volatile semiconductor memory elements 2〇1, 2〇2 is 0.5V, It can be enough to move. Fig. 7C shows the case where the control signal terminal voltage vs is set. The initial state of the floating gate FG at the time of erasing, according to (Formula 2), becomes VFG (Erase) = 0.1 x 6 (F) = 〇.6(F) 24 201001420 The final state of the floating gate FG is 6V_5V=1 v Therefore, the amount of change becomes +0.4V. Further, the initial state of the floating gate FG at the time of writing becomes VFG (?r ogram) = (1) x 6 (F) + 〇.8 x 6 (F) x 0.5 = 3.0 (V) according to (Expression 3). The final state is erased at FG = 1 V. Therefore, when FG = 1 v, the amount of change becomes -2.0V. Therefore, take the initial state of the floating gate FG of 0, and according to (Formula 4_i), become KFG("0")=0.1(F)x 1(F)- 2.0(7)= -1.9(F) 'The initial state of the float FG of reading 1 is FFG('T') = 〇. 1X l(F) + 〇.8 X l(F)x 0.5 + 0.4(F according to (Formula 4-2) ) = 0.9 (K) Therefore, since the threshold ' of the non-volatile semiconductor memory elements 20 1 and 202 ' is 0.5 V, the margin of the "丨" reading operation becomes severe (the allowable range of reading) Narrowed). However, in this case, if the threshold values of the non-volatile semiconductor memory devices 20 1 and 202 are set to be around 0 V, they can be read. When the source is extremely common, there is an optimum voltage near VS=6V to 7V. [Embodiment 3] Another embodiment is further shown in Fig. 8.

Therefore, if the memory cells are separated from the SRAM portion 100, the memory can be In the same manner as the SRAM unit 100. When the entire memory unit simultaneously performs data transfer, the current flowing into the SRAM unit 100 is excessively concentrated, and a large current flows. In this case, if the activation signal SET is activated to the signal SET The input timing of the input terminals is sequentially shifted, and the activation timing of each of the memory cells MA11 to MAmn is shifted, and the peak current can be suppressed.

The charging of the data line DL and the data line inversion signal line DLB is pre-charged in the same order as the pre-charge signal pRE by another data line pre-charging circuit. Regarding the data line precharge circuit, the precharge circuit 600 and the like shown in the next embodiment can be applied. The detailed description will be described later. At time t22', "n" is input to the input terminal of the precharge signal PRE, and the precharge signal PRE becomes "Η". The charging of the transistors 301 and 302 is stopped, and the pre-charging is completed. Here, the signal input from "l" gradually becomes "Η" at the input terminal of the sensing signal SEN, and since the sensing signal s EN is gradually changed from "L" to "Η", the sensing of the high-sensitivity sense amplifier 300 is performed. The amplifier is activated. At this time, the data written in the memory unit 200 is "", the data, since the non-volatile semiconductor memory device 20 1 is in the off state, 202 is in the on state, and the common source S is the reference potential (0 V). The current flows through the non-volatile semiconductor memory device 202 at the common source s, and the small voltage difference between the signal line Bit 31 201001420 and the BitB cannot be detected, which may cause a malfunction. To avoid malfunction, the rising waveform of the sensing signal SEN is as shown in the figure. As shown, it needs to rise slowly. Ideally, the voltage of the input terminal of the sensing signal SEN is preferably set near the threshold of the transistor 305 to cause the transistor 305 to operate at a low current. However, the operating current of the transistor 305 In relation to the sensing speed, the sensing speed is slowed down when the transistor 3 〇5 is operated with a low current and the current is limited. At time t23, the input terminal of the sensing signal SEN is input ΓΗ", and the sensing signal SEN becomes " H". During this time, the potential of the signal lines Bit and mtB is determined. At time t24, after "Η" is input to the word line WL in the state where the potentials of the signal lines Bit and BitB are determined, the word line WL becomes "η". Since the word line WL becomes "Η", the transistors 306 and 307 are activated and charged by the signal lines Bit and BitB 'by this' data line DL and the data line inversion sfl line DLB potential is determined to 'end reading action.

Further, the memory unit 2A is the same, and is connected to the high-sensitivity sense amplifier 400 through the signal lines Bit and BitB. The high-speed sense amplifier 400 includes sensing NMOS transistors 40 1 and 402, sense amplifier activating NMOS transistors 403 and 404, and 32 201001420 to transmit (read) the sensed data to the data line DL and The data line inverts the transfer transistors 405, 406 of the signal line DLB. The gate of the transistor 40 1 is connected to the drain of the signal line BitB and the transistor 402, and the source is connected to the drains of the transistors 403 and 404. The gate of the transistor 402 is connected to the drain of the signal line Bit and the transistor 401, and the source is connected to the drains of the transistors 403 and 404.

An embodiment of a high-sensitivity sense amplifier 33 201001420 400 that replaces the high-sensitivity sense amplifier 300 is provided. The difference between the high-sensitivity sense amplifier 400 and the sixth embodiment shown in Fig. 11 is that the precharged transistors 301 and 302 included in the high-speed sense amplifier 300 are deleted, and the activated transistors are again separated into 403 and 404. Further, the precharge circuit 600 is provided only on the data line DL and the data line reverse signal line DLB side. Further, after the precharge circuit 600' inputs "L" to the input terminal of the input precharge control signal pre, the precharge control signal Pre becomes "L". Thereby, the data line DL and the data line reverse signal line DLB can be charged through the transistors 601, 602 '.

Next, the operation will be described with reference to Fig. 14. This figure is a timing chart showing the operation of the configuration shown in FIG. First, pre-charging starts at time t31, and inputs "input" at the input terminal of the pre-charge signal, the sensing signals SEN, and SENd, "pre-charge signal coffee, sensing signal § SENd" When it becomes "L", the word line WL becomes. 34 201001420 406 becomes conductive, pre-charge circuit 600

Further, the potential is slightly lower than the level of the Η", because the potential of the word line WL is "η" in the word line WL, and the input 406 is turned off. Further, the potential of the "Η" level is sensed. When the level is slightly lower, the transistors 405 and 40 input the signal SEN at the input terminal of the sensing signal SEN to become "η". At this time, the transistor 403 is made to operate at a constant current, or the transistor having a small capacity of the transistor is used to reduce the drain current. Thereby, the sensitivity of the sensing operation is increased, and the small potential difference between the signal lines Bit and BitB is expanded. Input "η" at the input terminal of the sensing signal SEN, and the sensing signal SEN becomes "Η". After the potential difference between the signal line Bit and BitB is increased to some extent, at time t33, "H" is input to the input terminal of the sensing signal SENd, and after the sensing signal SENd becomes "H", the potentials of the signal lines Bit and BitB are rapidly determined. Here, "η" is input to the input terminal of the word line WL, and the potential of the word line WL becomes "H", and the transistors 405 and 406 are completely turned on. The potential of the 'data line DL' and the data line inversion signal line DLB is determined. The determined potential is input to the amplifier unit 7A, and the amplifier unit 700 high speed 35 201001420 determines that the data is latched and the reading is completed. [Embodiment 8] Embodiment 8 of the embodiment modified in the seventh embodiment is shown in Fig. 15. In the part changed in the eighth embodiment, the same portions are denoted by the same reference numerals. The description of the seventh embodiment will be omitted. The high-speed sense amplifier 400 and the precharge circuits 600 and 700 shown in the seventh embodiment are the same, but the memory unit 2〇〇c is different from the memory unit 200a. The source of the non-volatile semiconductor memory devices 2〇丨 and 2〇2 in the memory unit 200a' is directly connected to the common control signal terminal s, but is connected to the common control signal terminal 8 through the resistor in the memory unit 200c'. . The memory unit 200c further includes resistors 2〇5 (first resistor) and 2〇6 (second resistor)'. The source passivation resistors 205 and 206 of the nonvolatile semiconductor memory devices 2A and 2〇2 are connected to the control unit. Signal terminal s. Since the resistors 205 and 206 are provided, even if the control signal terminal S is a common terminal, a sufficient operation margin (reading tolerance range) can be secured. As described in the second embodiment, after the control signal terminal s is a common terminal, the write erase voltage needs to be set to about 6V to 7V. Therefore, there is a case where the amount of injection of electrons or holes is small, and the read margin is reduced, and it is necessary to pay attention to the optimization of the voltage. In the present embodiment, for example, the nonvolatile semiconductor memory device 2〇1 is written (electron injection), and the nonvolatile semiconductor memory device 2〇2 is erased (hole injection), and the control signal terminal is considered. S applies 8V. For writing non-volatile semiconductor memory elements 2〇1, due to the flow 36 201001420

In the part changed in the ninth embodiment, the same reference numerals are attached to the unaltered portions. The description will be omitted with reference to the second embodiment. A high-sensitivity sense amplifier 500 (signal holding portion) in place of the SRAM portion 1 (sensing portion) shown in the second embodiment is provided. Further, the memory unit 2A is the same, and is connected to the high-sensitivity sense amplifier 5A via the signal lines Bit and BitB. An embodiment in which a high-sensitivity sense amplifier 5A that replaces the SRAM portion 1 is provided is provided. The form of this figure is a high-sensitivity, high-speed sense amplifier as the local sensitivity sense amplifier 500, and a high-sensitivity and high-speed sense amplifier function' has a latch function. The high-sensitivity sense amplifier 5A is provided with PM〇s transistors 501, 502, 503, 504, and 505. The gate of the transistor 501 (power supply transistor) is connected to the terminal of the activation signal SET, the drain is connected to the power source, and the source is connected to the drain of the transistor 5〇2 and 37 201001420 503. The gate of the transistor 502 is connected to the source of the signal line Bit and the transistor 503. The gate of the transistor 503 is connected to the source of the signal line BitB and the transistor 502. The gate of the transistor 504 is connected to the word line WL, the drain is connected to the data line DL, and the source is connected to the source of the transistor 502. The gate of the transistor 505 is connected to the word line WL, the drain is connected to the data line inversion signal line DLB, and the source is connected to the drain of the transistor 503. Ρ Μ O S transistor 5 0 1 ' is the activation signal SET for the setting and activation of the sense amplifier at the gate input.
