Abstract
A semiconductor memory device comprises: a memory transistor; a first wiring connected to a gate electrode of the memory transistor; and a control device that executes a read operation to read data of the memory transistor and a write operation to write data in the memory transistor. In the read operation or the write operation, the control device: increases a voltage of the first wiring to a first voltage from a first timing to a second timing; and adjusts a length from the first timing to the second timing corresponding to at least one of a voltage of the first wiring, a current of the first wiring, and an amount of charge flowed through the first wiring.
