Abstract
A computer memory subsystem is comprised of one or more Dynamic Random Access Memory (DRAM) arrays with on-chip sense latches for storing data outputted from the DRAM, an on-chip Static Random Access Memory (SRAM) functioning as a Distributed Cache and an on-chip multiplexor. A first data bus interconnects the sense latches, the SRAM and the multiplexor. A second data bus interconnects the multiplexor and the SRAM. A memory controller generates signals which cause information to be extracted from the DRAM while the contents of the SRAM is unchanged or vice versa.
