ABSTRACT:
A semiconductor memory device includes a memory cell unit, word lines, a driver circuit, and a voltage generator. In the memory cell unit, memory cells having a charge accumulation layer and a control gate are connected in series. The word lines are connected to the control gates. The driver circuit selects the word lines. The voltage generator generates a first voltage and a second voltage lower than the first voltage. The first voltage is used by the first driver circuit to transfer a voltage to the unselected word line. The second voltage is used by circuits other than the first driver circuit.
