ABSTRACT:
A control system for a disk cache memory is disposed between a main memory unit and a disk unit for storing a record of data from the disk unit. The control system is designed such that when an input/output instruction is issued from a CPU while data loading is being performed from the disk unit to the cache memory, it interrupts the data loading once so that an input/output instruction from the CPU can be executed, thereby considerably reducing the time of wait for execution of the input/output instruction.
