Abstract

See full text

A memory controlling apparatus retains time information prepared based on performance of a memory and a processor, and determines timing of signal exchange between the memory and the processor based on the time information. An access time to the memory is reduced while maintaining a flexibility to a change of the access time due to increase of memory capacity or reconfiguration of the memory.
