Abstract
According to one embodiment, selection gates include an extract portion, a first portion, and a second portion. A predetermined potential is transmitted from the extract portion to the first portion. The predetermined potential is transmitted from the extract portion to the second portion with a delayed time to the first portion. A threshold voltage of a first selection transistor is different from a threshold voltage of a second selection transistor. The first selection transistor includes a semiconductor body disposed in the first portion as a channel. The second selection transistor includes the semiconductor body disposed in the second portion as a channel.
