Assignee: KIOXIA CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 8:
9. The device according to claim 1, wherein
the control circuit is further configured to start outputting a first voltage to the first word line via the second node in a verify operation on the memory cell,
the control circuit is further configured to transmit a first signal to a control end of the first switch and transmit a second signal to a control end of the second switch,
a period during which the first voltage is output to the first word line includes: a first period during which a voltage of the first signal is at a first level and a voltage of the second signal is at a second level; a second period which is after the first period and in which the voltage of the first signal is at a third level and the voltage of the second signal is at a fourth level; and a third period which is after the second period and in which the voltage of the first signal is at the first level and the voltage of the second signal is at the second level,
the second level being lower than the fourth level if the first level is higher than the third level, and
the second level being higher than the fourth level if the first level is lower than the third level.
