Memory control circuit and integrated circuit including branch instruction detection and operation mode control of a memory

摘要

The memory unit is compatible with a plurality of operation modes. The plurality of operation modes include the normal mode allowing access and the standby mode consuming a lower power than the normal mode. The branch detection section detects a branch instruction from an instruction fetched from the memory unit by the CPU. The mode control section changes an operation mode of the memory unit according to a detection result by the branch detection section.
