SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a memory mixing LSI in which current consumption at the time of a standby state can be reduced. SOLUTION: At the time of a sleep mode, after holding data of a logic circuit 2 is evacuated to a memory circuit 3 under control of a transfer control circuit 6, supplying operation power source voltage to the logic circuit 2 from a logic power source 4 is stopped.
