PROBLEM TO BE SOLVED: To reduce a leak current of a system LSI having a memory mounted thereon, and reduce power consumption in a standby state. SOLUTION: The semiconductor device has a power switch in a logic circuit of the system LSI, and reduces a leak current by shutting off the switch in the standby state. At the same time, an SRAM circuit reduces the leak current by controlling a substrate bias, setting the power switch for a read amplifier or write amplifier, and shutting off the switch.
