Zusammenfassung:A semiconductor memory device includes memory cells and a voltage generating circuit for generating a voltage for memory cells. The first voltage generating circuit includes a first diode connected between first and second nodes, a first transistor connected between the output terminal and a third node and having a gate connected to the second node, a second transistor connected between the third node and a fourth node and having a gate connected to the second node, a third transistor connected between the output terminal and the first node and having a gate connected to the fourth node, a second diode connected between the first and fourth nodes, and a charge pump circuit configured to supply a voltage to the fourth node. The first voltage generating circuit functions to adjust the generated voltage when it overshoots a desired value which may be caused by capacitive coupling with adjacent wirings.
