ABSTRACT:
In a data processing system which includes a central processing unit and one or more main memory units for storing program software instructions and program data, logic is provided within the CPU to signal the main memory units, comprised of semiconductor random access memory chips, that a memory refresh operation can be performed. The logic is organized such that the memory refresh operation signal may be given to the main memory units in parallel with and without detracting from other CPU operations. Further, logic is provided within the CPU to interrupt the CPU normal processing and perform a memory refresh operation if one has not been performed with a predetermined time period. Logic is provided within each main memory unit to accept the memory refresh signals from the CPU and to discard those memory refresh signals that would refresh the memory more frequently than required to retain the memory contents thus reducing main memory power consumption.
