Circuit and method for an SRAM with reduced power consumption

摘要

A circuit and method for providing an SRAM memory with reduced power consumption, the SRAM memory particularly useful for embedding SRAM memory with other logic and memory functions in an integrated circuit. A lower supply voltage is provided to the peripheral circuitry for the SRAM memory. A level shifter circuit is provided coupled to the lower power supply and outputting a higher supply voltage. An array of SRAM memory cells that may comprise 4T, 6T or 8T static RAM memory cells are coupled to the higher supply voltage during read and write operations. Operating the peripheral circuitry of the SRAM memory at the lower supply voltage achieves reduced power consumption for the SRAM memory and the integrated circuit.
