ABSTRACT:
In a memory system, which includes a dynamic random access memory (DRAM) that has to be precharged before the contents thereof can be selectively read out into a static register, there is provided means for reading the memory contents of the memory cells of a part or the whole of a row of memory cells of the DRAM into the static register while concurrently precharging the DRAM for a subsequent read-out command. This reduces the overall cycle time of the memory array since read-out of the static register can occur during precharge.
