    • The present invention provides a computer motherboard having an Intel P54C compatible processor socket and a control chip having specifically arranged data pins and address pins which allows a short signal path arrangement from the processor socket to a cache tap RAM and a cache data RAM. The computer motherboard comprises a four-layer printed circuit board, a processor socket, a cache data RAM, a cache tag RAM, and a control chip. All these components are connected by using a high-order-bit data bus, a low-order-bit data bus, and an address bus through the top and bottom layers of the circuit board. The cache data RAM is positioned on the right side of the processor socket. The control chip is positioned on the top side of the cache data RAM and on the top-right side of the processor socket. It comprises an address section positioned at a bottom-middle portion of the control chip, a high-order-bit data section positioned at a bottom-right corner of the control chip, and a low-order-bit data section positioned at a bottom-left corner of the control chip. The cache tag RAM is positioned between the processor socket and the cache data RAM.

    • A layout structure of a central processing unit (CPU) that supports two different package techniques, comprising a motherboard that comprises the layout structure and a layout method. The layout structure of the preferred embodiment according to the present invention from up to down sequentially places a top signal layer, a grounded layer, a power layer having a grounded potential, and a bottom solder layer in the area where the signals of the CPU are coupled to the signals of the control chip, so that the signals that are placed on the bottom solder layer can refer to a grounded potential area of the power layer. Therefore, part of signals of the CPU that are coupled to the control chip can be placed on the bottom solder layer. Since the preferred embodiment of the present invention provides more flexibility in the placement design, a layout structure that supports the Pentium IV CPUs of different package techniques can be designed on the motherboard of the 4 layers stack structure, and these two CPUs can be supported by the same control chip.

    • A memory control system for controlling write-enable signals. The memory control system has a first memory slot having a write-enable pin thereon, a second memory slot having a first write-enable pin and a second write-enable pin thereon and a control chipset having a write-enable pin and a dual-purpose write-enable/memory-parity-data pin thereon. The write-enable pin of the control chipset is connected to the write-enable pin of the first memory slot and the first write-enable pin of the second memory slot. The write-enable/memory-parity-data pin of the control chipset is connected to the second write-enable pin of the second memory slot. In this invention, since the design of the write-enable system is more flexible, length of trace line on a computer board can be greatly reduced. In addition, the system permits the incorporation of one cycle (1T) timing into design of memory access commands.

    • A suspend-to-RAM controlling circuit includes a RAM (random access memory) controller, a logic circuit and at least one RAM module. The RAM controller has a controlling pin connected to the logic circuit. Each of the RAM modules has a first enable pin and a second enable pin connected to output pins of the logic circuit. The RAM module is driven to the STR (suspend-to-RAM) state after receiving an STR signal from the logic circuit. Therefore, the RAM controller can provide STR signals to a plurality of RAM modules by only one controlling pin in incorporation with the logic circuit.
