Abstract

See full text

A memory device includes a top select cell, a top dummy cell and a string of memory cells. The top select cell has a first terminal coupled to a bit line and a control terminal coupled to a top select line. The top dummy cell has a control terminal coupled to a top dummy word line. The string of memory cells has control terminals coupled to respective word lines. A method operating the memory device includes prior to a program operation, applying a pre-pulse voltage to the top dummy word line, the top select line and the bit line while applying a low voltage to the word lines, and then sequentially applying the low voltage to the top dummy word line, the top select line and the bit line while applying the low voltage to the word lines.
