Description

Conversion card for memory card signal and main board using the conversion card

technical field

The invention relates to a conversion card and a main board, in particular to a conversion card for storing card signals and a main board using the conversion card.

Background technique

DDRII has always been regarded as a revolutionary substitute for the current DDR memory card standard, because DDRII breaks through the frequency limitation of DDR (DDR 400, 200MHz pulse frequency), and has high bandwidth availability, accommodates more chipsets and lower power consumption features.

Although in terms of specifications and electrical characteristics, DDRII is indeed superior to DDR. For example: higher bandwidth (4-bit vs. 2-bit prefetch), lower driving voltage (1.8V vs. 2.5V), internal interrupt resistor design (On die termination), etc. However, DDRII still cannot completely replace the existing DDR, because DDR memory cards are still commonly used in the existing motherboard equipment of consumers. In order to support the use of DDRII and DDR at the same time, the chipset of the motherboard needs to be redesigned. For example, Intel's 915P and 915G chipsets can also use DDR memory cards in addition to supporting DDRII memory cards. Therefore, there are still a considerable number of 915P/G motherboards on the market that have both DDR and DDRII memory slots, and there are quite a few motherboards that only provide DDR slots.

In general, motherboards that support both DDRII and DDR chipsets may be designed in the following three forms:

1. Provide 4 sets of slots that support DDR memory cards.

2. Provide 4 sets of slots that support DDRII memory cards.

3. Provide 2 sets of slots supporting DDR memory cards and 2 sets of slots supporting DDRII memory cards.

Since DDR and DDRII memory cards are incompatible in pins and structures, the above-mentioned design method 1 can only support DDR memory cards, but cannot use DDRII memory cards. The above-mentioned design method 2 can only support DDRII memory cards, but cannot use DDR memory cards. Above-mentioned design mode 3 is then shown in Figure 1, chipset 7 can support DDRII and DDR use, and the first memory card slot 71 can be used for DDRII memory card insertion, and the second memory card slot 73 can be used for DDR memory card Plug-in use, the design method shown in Figure 1 is obviously a better choice in the current transitional period from DDR to DDRII, so that users can plug in DDR or DDRII memory cards on the motherboard according to actual usage needs. However, in the above-mentioned design mode 3, the main board obviously cannot meet the user's demand for large-capacity storage space, because in this mode, the user can only plug in two DDR or two DDRII memory cards at the same time, that is, in the In Fig. 1, the user can only select one of the first memory card slot 71 or the second memory card slot 73 to use, and the corresponding other group of memory card slots can only be in an idle state, which actually forms a kind of waste.

Detailed ways

Please refer to FIG. 2 , which shows a layout and connection diagram of components on the motherboard of the preferred embodiment of the present invention. In this embodiment, when the motherboard supports memory cards with different specifications of DDRII and DDR at the same time, a solution is proposed to convert the signal of the DDRII memory card into a signal compatible with the DDR memory card. Chipset 1 in the mainboard as shown in Figure 2 can support DDRII memory card and DDR memory card use, chipset 1 has provided two first memory card slots 11 for DDRII memory card plug-in use, and two second The memory card slot 15 is used for inserting a DDR memory card.

The first memory card slot 11 is used to support the use of DDRII memory cards. Through the control of the chipset 1, it can be used to transmit two sets of DDRII memory card signals to the first memory card slot 11, such as -RASA, -CASA, -SWEA , +/-CLKA[0:2], MDA[0:63], MAA[0:13], DQSA[0:7], -DQSA[0:7], DQMA[0:7], -CSA[ 0:1], CKEA[0:1] and -RASB, -CASB, -SWEB, +/-CLKB[0:2], MDB[0:63], MAB[0:13], DQSB[0:7 ], -DQSB[0:7], DQMB[0:7], -CSB[0:1], CKEB[0:1] and other two groups of DDRII memory card signals.

The second memory card slot 15 is used to support the use of DDR memory cards, and is used to transmit two sets of DDR memory card signals to the second memory card slot 15 through the control of the chipset 1, such as -RASA, -CASA, -SWEA , +/-CLKA[0:2], MDA[0:63], MAA[0:13], DQSA[0:7], DQMA[0:7], -CSA[0:1], CKEA[0 :1] and -RASB, -CASB, -SWEB, +/-CLKB[0:2], MDB[0:63], MAB[0:13], DQSB[0:7], DQMB[0:7] , -CSB[0:1], CKEB[0:1] and other two groups of DDR memory card signals. The DDR memory card signal transmitted by the second memory card slot 15 only has less -DQSA[0:7] and -DQSB[0:7] signals than the first memory card slot 11, and the rest of the signals are compatible with DDRII memory card signal transmitted by the first memory card slot 11.

The first memory card slot 11 is used for plugging in a DDRII memory card, and the first memory card slot 11 cannot directly be plugged in for a DDR memory card due to differences in pins and structures. And the present embodiment promptly provides the conversion card 13 of a memory card signal and can be used for plugging in the first memory card slot 11 and uses, and the main effect of this conversion card 13 can be the DDRII memory card that the first memory card slot 11 transmits After the signal is processed by pin and structure conversion, the output becomes a DDR memory card signal, and the first memory card slot 11 can be inserted under the conversion card 13 to overcome the limitations on the pin and structure and further support DDR. The memory card is plugged in and used, and how the converter card 13 works will be further explained below.

Please refer to FIG. 3 , which is a schematic structural diagram of a memory card signal conversion card of the present invention. The conversion card 13 includes a card body 133 , a first interface 131 and a second interface 132 , and the first interface 131 and the second interface 132 are respectively disposed on the card body 13 . The first interface 131 is compatible with DDRII memory card signal transmission, and includes a plurality of first transmission terminals 1311 , and transmits DDRII memory card signals through these first transmission terminals 1311 . The second interface 132 is compatible with DDR memory card signal transmission, and includes a plurality of second transmission terminals 1321 , and transmits DDR memory card signals through these second transmission terminals 1321 .

And between the first interface 131 and the second interface 132, it is used to transmit -RASA, -CASA, -SWEA, +/-CLKA[0:2], MDA[0:63], MAA[0:13], DQSA [0:7], DQMA[0:7], -CSA[0:1], CKEA[0:1] and -RASB, -CASB, -SWEB, +/-CLKB[0:2], MDB[0 :63], MAB[0:13], DQSB[0:7], DQMB[0:7], -CSB[0:1], CKEB[0:1] and other first transmission terminals 1311 of the same signals and The second transmission terminals 1321 are respectively electrically connected through the card body 133 , so that the second interface 132 can transmit DDR memory card signals. In this embodiment, the first interface 131 of the conversion card 13 is a gold finger pin, the second interface 132 is a gold finger slot, and the card body 133 can be a printed circuit board (PCB).

Therefore, when the conversion card 13 is inserted into the first memory card slot 11, its first interface 131 is directly inserted into the first memory card slot 11. At this time, the first interface 131 and the first memory card slot DDRII memory card signals can be transmitted between 11, and the DDRII memory card signals transmitted by the first interface 131 are converted and processed to be compatible with DDR memory card signals to the second interface 132 through the conversion card 13, so that the second interface 132 can Directly support DDR memory card plug-in use.

For existing motherboards that support DDRII and DDR memory cards with different specifications, the motherboard can only use DDRII memory cards or DDRII memory cards at the same time, but cannot use DDRII memory cards and DDR memory cards at the same time, so that the motherboard cannot be used. It is for users to expand and use to the maximum memory capacity. The conversion card 13 provided in the present embodiment just can solve this type of problem in the prior art, as shown in Figure 2, although the first memory card slot 11 itself can only support the use of DDRII memory card, when the present invention When the memory card signal conversion card 13 is plugged into the first memory card slot 11, a DDR memory card can be plugged into the second interface 132 of the conversion card 13, so the first memory card slot 11 is inserted into the conversion After the card 13, it can be used to support the DDR memory card, and then cooperate with the second memory card slot 15 to directly insert the DDR memory card, and the main board in Fig. The capacity of the card is expanded to the maximum supported capacity of chipset 1. In addition, most of the current computer motherboards only have slots that support DDRII memory cards, and the conversion card 13 of the memory card signal of the present invention can provide users with DDR memory cards on motherboards that can only support DDRII memory cards. The flexibility of use is greatly improved to meet the needs of different users.

In the above-described embodiment, the conversion card 13 of the memory card signal of the present invention is used to convert the first interface 131 of the compatible DDRII memory card signal into the second interface 132 of the compatible DDR memory card signal, thereby realizing the support of DDRII on the motherboard. The first memory card slot 11 of the memory card is used to transfer the purpose of the DDR memory card, yet the transfer card 13 of the memory card signal of the present invention can also realize the opposite conversion, that is, it can be used to convert the compatible DDR memory card signal on the main board. The interface is converted into an interface compatible with the DDRII memory card signal, so as to achieve the purpose of switching the DDRII memory card on the memory card slot supporting the DDR memory card on the motherboard. The opposite conversion process is basically the same as the principle and working process described in this embodiment, and will not be repeated here.
