Abstract
A semiconductor device includes an internal circuit, a power supply control circuit which controls supply of a power supply to the internal circuit upon receipt of a first control signal, and a control signal generation circuit which outputs the first control signal upon receipt of a second control signal. The control signal generation circuit does not deactivate the first control signal when an inactive period of the second control signal is equal to or less than a first period and deactivates the first control signal when the inactive period of the second control signal is more than the first period.
