Abstract
A reset pulse signal generating circuit includes an output node with an output circuit connected thereto that outputs the reset pulse signal, and a first MOS transistor having a first conductivity type connected between a first power supply and the output node. The first MOS transistor is turned on responsive to a write signal. The circuit further includes a second MOS transistor having a second conductivity type connected between the output node and a second power supply, and a power supply transition detector connected to the first and second power supplies and the second MOS transistor. The power supply transition detector outputs a transfer signal having a level determined by a level of the power supplies when the write signal is in an inactive state. The power supply transition detector outputs the transfer signal having a predetermined level when the write signal is in the active state.
