Title: Memory device with split power switch and related methods
Inventor: LIH YOLIN
IPC: G11C11/419
Filed: 2008-01-30
Abstract: A memory device having a split power switch is provided to improve the writeability of static random access memory (SRAM) cells without adversely compromising their stability. For example, various split power switch circuits are used to permit the voltage or current of a power supply line connected with one side of an SRAM cell to drop during write operations. This drop weakens one side of the SRAM cell and reduces the drive-fight between transistors of the SRAM cell and external write circuitry. As a result, the minimum voltage for writing new logic states into the SRAM cell is reduced to permit overall lower operating voltages for the SRAM cell and related circuitry. By continuing to maintain a second side of the SRAM cell at the reference voltage or current, the SRAM cell can successfully switch to a newly written logic state.
