Sequence circuit and semiconductor device using sequence circuit |
摘要 |
A semiconductor device includes a word line that is reset to a negative voltage when the word line is unselected. The semiconductor device further includes a sequence circuit that clamps the word line to a first fixed voltage, until a fixed power-supply voltage that is supplied to a memory cell connected to the word line reaches a second fixed voltage, at a time of starting power supply. Thus, the semiconductor device can prevent a negative power-supply voltage used for resetting the word line from rising, and can reduce consumed energy.
