Method for overlapping memory accesses

Abstract:

Improved methods and systems for accessing a memory in a computer are disclosed. In one embodiment, the true and complement portions of a differential write clock signal are employed as two single ended clock signals for independently controlling different memory chips in a memory system. For example, in a memory system having two memory chips, one memory chip is configured to use the true write clock signal and the other memory chip is configured to use the complement write clock signal. Employing the differential write clock signal as two single ended clock signals allows overlapping of write and read operations across multiple memory chips, reducing the time needed for accessing memory. Accordingly, the disclosed methods and systems provide a more efficient memory system that can be used to improve the operation of a computer.
