Abstract
A semiconductor memory having a plurality of programmable memory cells includes discharge circuits for discharging a residual charge which remains on a digital line and a signal line coupling the digit line to a sensing amplifier after a programming of a memory cell is completed. The discharge circuit is coupled to the digit line on the signal line and is activated after the programming is completed. The discharge circuit is inactivated when the programmed data is verified.
