Abstract
Systems and methods are provided for limiting a negative bit line voltage in a SRAM cell. A voltage limiter circuit may be implemented in a write driver to control the magnitude of negative voltage imposed on a bit line. The voltage limiter circuit can produce the required magnitude of negative bit line voltage at lower operating voltage levels. The voltage limiter circuit can also limit the magnitude of negative bit line voltage to not exceed a predetermined value. The reduction of the magnitude of the negative bit line voltage can reduce the active power of a SRAM cell.
