Field of the Invention The present invention relates generally to semiconductor logic circuits, and more particularly to 20 low power static BACKGROUND OF THE INVENTION Static random access memory (SRA) is an electronic form of data storage that retains its data as long as it is supplied. Static ram is widely used in all electronic applications. In the way of the device, and especially in the convenience of portable or handheld applications, and The use of performance device applications. In portable or handheld cluster applications, such as mobile phones, SRAM provides stable data retention without the need to support circuits, thus maintaining its low complexity while maintaining a robust data retention. However, as the processing technology advances and the transistor is scaled down, the leakage current of the transistor during power-down increases significantly. Therefore, the static power consumption due to the leakage current represents a larger portion of the total power consumption and It has become a serious issue in the design of VLSI (very large integrated circuit). The existing technology for reducing leakage is to use a power supply and/or ground source transistor to supply power to some devices, for example, a The output stage, (ie, the driver), as shown in Figures 1 and 2. The power transistor is turned off to cut off the power and/or ground to the output stage to thereby significantly reduce leakage current The use of source transistors provides a practical method of suppressing leakage currents. In an operational mode, for example, in ready mode, when they are turned on in normal operating mode When the 'source transistor is cut off. However, when designing the source transistor in this way, some issues should be carefully considered to avoid the following problems, such as rate degradation, excessive power consumption, data The security of information, and its other. It should be noted that when using the source transistor to make the design, when the wafer operation mode is changed to the normal operation mode by the standby mode (where the source transistor is cut), 6 The source-derived transistor may be susceptible to premature power and ground potential. 6 1290717 Another design issue with the use of source transistors is the frequent switching of the source crystals, thus cutting them off. Insufficient time periods to provide saved power. As a result of the gate capacitance of the source transistors with large charge and discharge, significant power is unnecessarily consumed. These shortcomings occur within the SRAM circuit and appear to a lesser extent within other memory circuits and are typically within many integrated circuits that include digital logic elements. There is therefore a need for systems and methods that reduce digital circuitry, such as SRAM, in which static power consumption affects the integrity of data or operations. The present invention satisfies four needs and others that overcome the inefficiencies of previously developed leakage suppression methods and circuits. 【明内^^】 Summary of invention 15

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 10 Detailed Description of the Preferred Embodiments * More specifically, reference is made to the drawings for the purpose of the present invention which is embodied by the apparatus generally shown in Figures 3 through 7. It will be appreciated that the configuration of the device and the details of the relevant components may vary, and the particular steps and sequences of the method may vary without departing from the concept as disclosed herein. • ... Figure 3 shows the invention - the argument in which the source transistor is used in the peripheral branch [since the white CMOS locker power supply. When the source transistor acts as ¥, the lock H can store and maintain data information. However, problems can arise when the source transistor is turned off, because in many applications, the latch maintains the data bit as long as the power supply is supplied to the device. The methods and circuits described herein are generally used to control the state of the source transistor in the latch, memory, and logic circuitry. The principle of the present invention is the early priming of the source transistor to help avoid logic circuit failure. The techniques and methods of the embodiments described herein provide for the early priming of the source transistor and other related methods. In some embodiments, different delays are provided, for example, in signal and circuit paths, and the use of different control signals, and others. Figure 4 illustrates an embodiment by way of example in which the address channel has a different signal delay, while Figure 5 reveals the signal timing. Considering the circuit of Fig. 4, it is assumed that the inverter INV31 is subjected to a high leakage current because it is generally larger than the device connected to the integrated circuit. A power transistor MPS31 is added to one of the PMOS source PMOS crystals to suppress the leakage current. It will be appreciated that an embodiment can be produced by the NMOS 10 source transistor, as shown in Figure 2 (MNS12). When a wafer select signal (CS) is illuminated (low priming signal, as shown in Figure 5), node A is at a low priming signal and actuates (turns on) the source transistor mpS31. The wafer select signal has another route to illuminate the address buffer to receive the address (ABUF). The received address is pre-decoded and node c becomes high after a delay of some 15 times. The precharge signal (PPRE) is not steered until node C becomes high to eliminate the quiescent current path. When all the gates 5, MNL31, MNL32, and MNL33 become high-level temples, the nodes are discharged by the skin and become low. The low potential of node D turns on the pM〇s transistor and causes the output node (OUT31) to be high. 2〇 It should be noted that the power supply line 1NV31 should be stabilized before the node 0 becomes the low level and the PMOS transistor INV31 is turned on. Therefore, the power transistor MPS31 must be turned on before the node D becomes the low level. In this circuit fabrication, 'because of power transistors, MpS3 Bu is controlled and motivated using the same signal', but 7^卩 suffers from different signal delays (ie, short signal delay), 21 1290717 MPS31 can be turned on earlier, thus turning Inverse (four) circuit, wide 3i, any fault. As shown in Figure 5, there is a timing margin between signal A and signal C (TMD to properly control the source transistor. • The other way to control the action of the source transistor is to utilize it. 5 different types of signals on the chip. For example, some non-synchronous signals, such as wafer singularity, advance the person to the wafer with a set time margin. Thus, information relating to the early arrival of the asynchronous signal, for example, the chip select_#, can be used to turn on the source transistor even if other inputs, such as an address, are at the rising or falling edge of the sync signal (10), for example, The clock was arrested and harvested 10 times. Figures 4 and 5 also show a way to prevent unnecessary priming and non-dynamic power source transistors. It should be noted that when the circuit pulsates and does not illuminate the power transistor too frequently, excessive power can be dissipated. 'This can occur, for example, when the source transistor is not between sequential accesses. Inspire the day. When the reaction is charged and discharged by the input capacitor, and the reaction is too frequent and is not actuated, additional power is consumed. To overcome this shortcoming, an argument of the present invention provides for the use of a non-priming 'even-no illuminating signal' to be actuated (i.e., sputum selection becomes inactive) at some delay. As in the first embodiment, even if the wafer 'ρρ ^ ^ port 唬 (CS) becomes high, and the node A potential becomes south after the desired signal delay ' (ie, 100 = microseconds), for example, reacts to one The delay circuit (labeled as "delay," in Figure 4) or other method of delaying the power supply from the source is introduced from the source transistor. In the example given, 'this sufficient delay ensures that The source transistor remains on for a short period after the wafer select signal returns 22 1290717. In the meantime, the source band is relatively inactive during the period, such as by the delay, so the correlation is reduced. Charging of the capacitor = the body is switched back and should be understood, because of the power loss of the source transistor. 5 Current to the logic circuit, due to its gate capacitance, the full consumption of the supply can be the main factor. Therefore, the power of the extension and discharge is actually in the ready mode, because when the cut is made = the wafer is guaranteed to be delayed in the delay of the coffee. In the case of μ (four), two: a late manner is generated. Whether it is static, = sister money, reaction to the receipt of variables or other money, and pelvic pain. It will be understood that the extension is expected to be - m, depending on the application of the circuit, in order to minimize the power dragon The _ _ _ argument is to provide a kind of robust delay period for the production of the money when it is allowed to make money. The _ 'the delay can be burned I is planned. 15 In the other part of the invention, The locker circuit (for example, the CMOS lock-off leakage current can be reduced to increase the source transistor and control without introducing the rate delay. Figure 3 illustrates a transistor with a NM〇S power source and PMOS ground. The CM〇s of the source transistor is locked. When the data stored in the CMOS lock does not need to be held, the 20-source transistor, for example, MNS2 and MPS2 in the example, can be powered off to eliminate the leakage path. However, in the case where the data stored on the CMOS locker should be maintained, then the source transistor cannot be powered down. According to the present invention, the gate potentials of the NMOS and PMOS source transistors (MNS2 and MPS2) Can be controlled by 23 1290717 Providing a voltage level different from those presented during normal operation. By way of example, the gate potential of the NMOS source transistor (MNS2) can be pulled from a pulled voltage (which is greater than Vdd (> Vdd)). The voltage is changed to the voltage Vdd (= Vdd), and the gate potential PMOS source transistor (MPS2) 5 can also be changed from Vss (= Vss) from a pulled voltage lower than Vss (<Vss). Therefore, the potential levels VVDD2 and VVss2 of (virtual voltage NNX) become Vdd-Vui(MNS2) and Vtp(MPS2), respectively, where vtn(MNS2) and Vtp(MPS2) are the threshold voltages of MNS2 and MPS2, respectively. The changed VVdd2 and Wss2 potential levels increase the threshold voltage of the CMOS latch transistor. For example, the body-to-source voltages of MPL21 and MPL22 are lowered by Vtn (MNS2), and the source-to-body voltages of MNL21 and MNL22 are respectively increased by Vtp (MPS2). The use of these voltage changes can result in an increased threshold voltage for the CMOS locker transistor and, therefore, the leakage current flowing through the CMOS lock can be suppressed. Figure 15 shows another logic circuit implementation example with an NMOS ground source transistor (MNS51) in an SRAM (Static Random Access Memory) cell. Deer understand that a similar circuit related to the bit line sense amplifier of DRAM (Dynamic Random Access Memory) can be used. In this fabrication, the virtual ground potential (VVSS5) can be arbitrarily controlled using a reference voltage (vREF) and an amplifier (e.g., ohms 20 sense amplifier (AMP5)). The ground potential is then switched between an active and inactive logic mode in response to a change in device mode, for example, when reflected by a select signal (eg, a wafer select (cs) or block select signal) Time. This reference voltage level can be set using different methods (e.g., fuse selection). One of the advantages of this technology is the controllability of the virtual ground bit 24 1290717 quasi (wSS5). It will be appreciated that a similar architecture may additionally or alternatively be fabricated for use in controlling the virtual I potential of the lock. In the CM〇s locker illustrated in Figure 3 above, the virtual power and ground level NMC)S and the PM ss source transistor's threshold dust are determined and uncontrollable. Such levels are sensitive to wafer operating conditions (e.g., temperature, voltage, and others) and are also susceptible to manufacturing process variations. For example, as the temperature increases, (10) the threshold voltage of the transistor decreases. Therefore, as the temperature increases, the difference between the actual and virtual power and ground levels decreases. Therefore, even if the leakage current is more severe in the south of H), the leakage suppression becomes less due to the threshold current. In contrast, this aspect of the invention provides for effective leakage suppression, as shown in Figure 6, because the reaction (4) virtual power and ground levels can be controlled. Any of these techniques can be adopted and appropriately controlled and regulated. The grounding source transistor is as thin as _(d) in the word line _ the kitchen that is turned on is sequentially controlled to prevent the access rate (also P) from deteriorating. In addition, the ground source transistor can be switched off after a certain delay by using a control signal (eg, wafer selection as described above in relation to Figure 4). 20 m quasi-reactive to desired operating temperature, voltage, and circuit processing The characteristics are set to (4) - the application given. When the chip select signal (CS) becomes low, node A51 becomes high (or a higher voltage than VDD to increase the mNS51's ability for faster reading) And the conduction hall 51. When the word line (WL) becomes high, a single line muscle or 25 1290717 is discharged according to the data stored in the CMOS locker and a normal reading or another access operation is available. The reaction is performed after the operation of the wafer is idle for a sufficiently long period of time. The delay-source transistor inactivation of the present invention is optionally applied by 5. The reduction of the source transistor is not necessary to cut the source. The length of the time period can be considered sufficient if one of the power storage will not be generated for a short period of time, or when the power consumption is reduced in comparison to the application and operation to compare to a smaller time period. 'After performing a read operation, after the memory cell is not accessed for a long time 10, the wafer select signal (CS) remains unchanged and the word line remains primed. In this case, because The word line is high and the pass gate transistors MNL53 and MNL54 are turned on. Therefore, the leakage from the one-line load (not shown here) to the pull-down transistor (MNL51 or MNL52) of the SRAM cell A current is added to the leakage current of the CMOS latch. Thus, in this case, after a certain delay determined by a signal or a combination of signals occurs, the block line level transitions to a low level and is used for The information of the word line can be stored in the register, and the ground source transistor (MNS51) is controlled to pull up one of the potentials of the virtual ground (vVss5). When a new operation is initiated, nodes A52 and A53 The potential level can be updated by turning on the word line and controlling the source transistor and being re-stored back to the previous state. Figure 6 shows an embodiment showing a circuit that includes two CMOS inversions The first inverter The output is coupled to the input of the second inverter, and the output of the second inverter is coupled to the wheel 26 1290717 of the second inverter. The sources of the PMOS transistors of the first and second inverters are Connected to a certain first node, and the sources of the NMOS transistors of the first and second inverters are connected to a second node. A power or power transistor is connected to the first node, and a ground or A ground source transistor is coupled to the second node. 5 the first access route (eg, read or write) is coupled to the output of the first inverter, and/or the second access route is Connected to the output of the second inverter.

In the - mode, except for the normal access mode, the access route is cut off earlier than the normal mode and the address is stored elsewhere, and when the access path (4) a certain control signal or command is turned on The stored address information is used. Figure 7 shows an example of implementation of a source transistor cluster. Responsive to the circuit. The use of the power is applied. Therefore, the total power usage can be reduced without causing instability in the operation of the circuit. By way of example, the avatar circuit exhibits the use of non-synchronous and synchronizing signals to control the source transistors of the respective groups. However, it should be understood that other mechanisms may also be employed to control the source transistors of the respective populations (e.g., delays from different steps and/or synchronization signals, delay offsets, and the like). A first logical group is represented by source transistors MNSG1 (power supply) and MPSG1 (ground source), which are reacted to asynchronous information and/or control signals, and are controlled by source control circuit 1. A second logical group is represented by source transistors MNSG2 (power supply) and MPSG2 (ground source), which are controlled by the source control circuit 2 in response to the synchronization information 2 and/or control signals. In this simple example, the first logical group receives an input signal and produces a transmission that is transmitted via one of the second logical group. One benefit of using an asynchronous signal that arrives earlier than the sync signal is to provide rapid actuation for the source transistor and thus provide a timing margin for the logic operation of 28 1290717. It should be appreciated that the arrival of the asynchronous signal cannot be predicted, and further, the asynchronous signal state may change even when the wafer is in the idle or ready mode. For a logical group (ie, logical group 1 in the graph), it is motivated before 5 other logical groups (ie, logical group 2 in the graph), source transistor states, eg, MNSG1 and MPSG1, utilized A control circuit (i.e., source control circuit 1) that is subject to control from asynchronous information is modulated for rapid priming. The circuit configuration provides additional timing margins for the second logic group, wherein the source transistor can be actuated in response to a combination of synchronization information and/or control. In this example, the source transistor supplies power to the second stage logic only when reacting to the wafer that begins an efficient operation. 15 20 It should be understood that 'source transistors can be clustered into more than two groups and the method is modifiable for use with single-source transistors as shown and dual power and ground source transistors. Although the above description contains many specifics, it should be understood that these are not to be construed as limiting the scope of the invention.
