Patent ID: 11894074
Assignee: KIOXIA CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 13:
14. The device of claim 10, wherein
in the verify operation of the first data, the controller
first charges the first sense node and the second sense node and then discharges the first sense node and the second sense node for a fourth time, before a determination is made as to whether or not the threshold voltage of the second memory cell transistor exceeds the verify low voltage of the second data, and
discharges the first sense node and the second sense node for a fifth time without charging the first and second sense node, after a determination is made as to whether or not the threshold voltage of the second memory cell transistor exceeds the verify low voltage of the second data and before a determination is made as to whether or not the threshold voltage of the first memory cell transistor exceeds the verify high voltage of the first data.
