CONTROL OF DUAL-VOLTAGE MEMORY OPERATION

Abstract:

An integrated circuit includes a memory and a system management unit. The memory has a memory array operating according to a memory power supply voltage and access circuitry coupled to said memory array operating according to a logic power supply voltage. The system management unit activates a first control signal to control an operation of the memory selectively in response to a magnitude of a difference in voltage between the logic power supply voltage and the memory power supply voltage.
