Abstract
A circuit includes a memory circuit, and a power management circuit having a first circuit. The first circuit is configured to, in response to a first state of the first power management control signal and a first state of the second power management control signal, control supply of a first supply voltage to the memory circuit in accordance with a first power mode control signal. The first circuit is further configured to, in response to a second state of the first power management control signal, store a state of the first power mode control signal, and control supply of the first supply voltage to the memory circuit in accordance with the stored state of the first power mode control signal. The power management circuit is configured to, in response to a second state of the second power management control signal, disable a part of the first circuit.
