Abstract:
A method of operation of a static random access memory (SRAM) storage element includes programming a value to the SRAM storage element prior to a power-down event. The method further includes, in response to a power-on event at the SRAM storage element after the power-down event, increasing a supply voltage of the SRAM storage element and sensing a state of the SRAM storage element to determine the value programmed to the SRAM storage element prior to the power-down event. In a particular example, an apparatus includes the SRAM storage element and control circuitry coupled to the SRAM storage element. The control circuitry may be configured to program the value to the SRAM storage element, to increase the supply voltage, and to sense the state of the SRAM storage element to determine the value programmed to the SRAM storage element prior to the power-down event.
