发明名称 Threshold detecting method and verify method of memory cells
摘要 According to one embodiment, a threshold detecting method for detecting threshold values of nonvolatile semiconductor memory cells comprises applying a preset voltage to a word line connected to the memory cells, and performing bit-line sense at two different timings during discharging of one of a bit line connected to the memory cells and a node corresponding to the bit line, while a potential of the word line is kept constant.
