ABSTRACT:
A method and apparatus for controlling the refreshing of a volatile memory is disclosed in which conflicts between a memory refresh operation, the requirements for access to the memory during a data processing operation and a power up or power down condition are resolved. When a conflict occurs, clock signals are generated to provide a contention refresh operation of the memory with minimum interruption to normal access time between the control processor and the memory.
