Abstract:
A memory access system for improving memory access when addressing dynamic random access modules (DRAMs). The memory access system includes a main memory and a memory controller. To improve memory access, both the memory controller and the main memory hardware remember the row address of the last access. Macro operation commands for fetch and store contain the last row address. The main memory hardware redrives that row address to the DRAMs after completion of an access, so that the memory controller need not provide a row address to the memory for each command of a command sequence.
