ABSTRACT:
The invention is an electronic circuit designed for incorporation on computer memory modules such as DDR DIMMs. It couples control signals such as address bits, bank selects, enable and even clock signals between the module input connector and the memory devices. The circuit provides low propagation delay, fast rise and fall times with no overshoot or undershoot, and significantly improves timing control compared to memory modules of the present art. Capacitive loading on the motherboard is typically much less than that provided by a single memory device input and is independent of the number of memory devices per bank or the number of banks of memory devices on the memory module. For multiple memory modules connected to the memory bus, capacitive loading is essentially N times the equivalent loading for a single memory module.
