ABSTRACT:
A discharge circuit for discharging bit lines of an array of semiconductor memory cells in which the array of bit lines are biased from a single bias line. The discharge circuit includes a discharge switch coupled to the bias line for discharging the bit lines and the bias line and a control circuit coupled to the discharge switch operative to turn on the discharge switch in response to the voltage on the bias line rising above a first predetermined level and then to turn off the discharge switch in response to the voltage on the bias line falling below a second predetermined level.
