SRAM device and a method of operating the same to reduce leakage current during a sleep mode

摘要

An SRAM device and a method of operating an SRAM device. In one embodiment, the SRAM device includes (1) an SRAM array coupled to row peripheral circuitry by a word line and coupled to column peripheral circuitry by bit lines and (2) a sleep mode voltage controller configured to provide both an array high supply voltage V_ADD that is lower than a high operating voltage V_DD and an array low supply voltage V_ASS that is higher than a low operating voltage V_SS to the SRAM array during a sleep mode.
