Abstract
The present application discloses a memory programming method, a memory device, and a memory system. The method comprises: performing a plurality periods of first increment step pulse programming (ISPP) on first memory cells to be programmed to a first programmed state, comprising: at a first stage of a first period of the first ISPP, performing programming suppression to the first memory cells; and at a second stage of the first period of the first ISPP, performing pulse programming to the first memory cells. As such, the programming speed of the memory cells corresponding to the first programmed state can be reduced, and a probability of the overprogramming of the memory cells corresponding to the first programmed state can also be reduced.
