Abstract:
A semiconductor memory device includes a memory string, first wirings electrically connected to the memory string, second wirings electrically connected to the first wirings, transistors electrically connected between the first wirings and the second wirings, and a third wiring connected to gate electrodes of the transistors in common. The memory string includes memory transistors connected in series. Gate electrodes of the memory transistors are connected to the first wirings. The semiconductor memory device executes a first read operation in response to an input of a first command set, and executes a second read operation in response to an input of a second command set. A first voltage that turns the transistors ON is applied to the third wiring from an end of the first read operation to a start of the second read operation.
