Abstract

The invention discloses a programming method for a semiconductor device and the semiconductor device. The semiconductor device includes a memory string, the memory string includes a plurality of first memory cells and first dummy cells stacked in sequence, each of the first memory cells is correspondingly connected to a word line, and the first dummy cells The gate of the first memory cell is connected to the first dummy word line; the method includes: in the precharge phase, inputting a precharge voltage to the word line corresponding to the programmed memory cell in the plurality of first memory cells, the programmed memory cell The unit is a storage unit between the storage unit to be programmed and the first dummy unit among the plurality of first storage units; in a programming phase, a programming voltage is input to a word line corresponding to the storage unit to be programmed. The embodiment of the present invention can reduce program disturb and increase boost potential.

Description

technical field [0001] The invention relates to the field of semiconductor technology, in particular to a programming method for a semiconductor device and the semiconductor device. Background technique [0002] A memory string in a semiconductor device generally includes a memory cell and a dummy cell, and residual electrons may exist in a channel of the dummy cell. When programming a memory cell in a memory string, a programming voltage needs to be input to a word line corresponding to the memory cell, and a high programming voltage will attract electrons in a channel of a dummy cell, resulting in program interference at the memory cell. Contents of the invention [0003] The invention provides a programming method for a semiconductor device and the semiconductor device, which can reduce programming interference and increase boosting potential. [0004] The present invention provides a programming method for a semiconductor device. The semiconductor device includes a me...
