Toggling power supply for faster bit line settling during sensing

Abstract

A memory device and associated techniques improve a settling time of bit lines in a memory device during a sensing operation, such as read or verify operation. Supply voltage from power supply terminals in the sense circuits is briefly toggled during a discharge of a selected bit line in response to a voltage on a selected word line being increased to a second word line level or higher. This helps to create an electrical path from the selected bit line through to a supply terminal for discharging the selected bit line such that a settling time of a voltage of the selected bit line is shortened in association with a target memory cell transitioning from a non-conductive state to a conductive state.
