Variable programming voltage step size control during programming of a memory device
摘要:
The memory device includes a control circuitry that is communicatively coupled to memory cells are arranged in a plurality of word lines. The control circuitry is configured to perform a first programming pass on a selected word line. The first programming pass includes a plurality of programming loops, each of which includes the application of a programming pulse (Vpgm). The programming pulse voltage is increased between programming loops of the first programming pass by a step size. The step size is a first step size between two programming loops of the first programming pass and is a second step size that is different than the first step size between two other programming loops of the first programming pass. The control circuitry is also configured to perform a second programming pass to further program the memory cells of the selected word line to the plurality of data states.
