    摘要: This disclosure is concerned with NAND flash memory, and proposes a method for programming the NAND flash memory. The NAND flash memory comprises a semiconductor channel layer, a first gate on a first side of the channel layer, and a plurality of second gates on a second side of the channel layer. Each second gate is associated with one memory cell and connected to one word line. The method comprises applying a first voltage to the first gate, and a pass voltage to one or more word lines, to allow charge to inject into the channel layer and form charge packets. Each charge packet is arranged next to one of the second gates. The method further comprises applying a programming voltage to the word lines, to move the charge packets from the channel layer into the memory cells associated with the second gates next to which they are arranged.
