Abstract:
A method of programming a memory device. The memory device includes a plurality of memory strings, each memory string including a top transistor controlled by a top select gate (TSG) and connected to a bit line (BL), a bottom transistor controlled by a bottom select gate (BSG), and memory cells between the top and bottom transistors, each memory cell connected to a word line (WL). The method includes applying program pulses to a memory cell of the memory device in a program phase, verifying a voltage value of the memory cell in a verify phase, receiving a suspend command and performing a suspend operation, applying a discharge pulse to the memory cell in a discharge phase to thereby discharge the memory cell, wherein the discharge pulse includes a voltage pulse to an unselected top select gate (TSGunsel), and suspending programming or verifying of the memory cell in a suspend phase.
