ABSTRACT:
An SRAM device and a method of powering-down an SRAM device. In one embodiment, the SRAM device includes (1) an SRAM array, (2) peripheral circuitry coupled to the SRAM array having voltage domains defined by a boundary and (3) a power-down voltage controller coupled to the SRAM array and the peripheral circuitry that separately regulates voltages of the SRAM array and the peripheral circuitry to reduce leakage current of the SRAM array and the peripheral circuitry at the boundary during a sleep mode.
