Abstract:
Discussed herein are systems and methods for charging a bit line (BL) during programming of non-volatile memory cells. An embodiment of a memory device comprises a group of memory cells including a first memory cell coupled to a first BL and a second memory cell coupled to a second BL, and a BL charging circuit that provides an inhibit signal to the second BL in response to a control signal to program the first memory cell. To provide the inhibit signal, the BL charging circuit apply a supply voltage to the second BL for an initial wait time and, after the initial wait time, apply a higher voltage than the supply voltage, until the inhibit signal reaches a value of the supply voltage. The first memory cells is programmed in response to the established voltage on the second BL.
