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

Claim 14:
15. The device of claim 2, wherein
the states include a fifth state, a memory cell transistor whose threshold voltage is included in the fifth state stores fifth data,
where at least a first condition, a second condition and a third condition are satisfied in the repetition of the program loop, the controller is configured to set a memory cell transistor to which the fifth data is to be written as the second program target,
the first condition is that a threshold voltage of the memory cell transistor to which the fifth data is to be written does not exceed a verify high voltage,
the second condition is that a verify low voltage of the fifth data is not determined as being exceeded in an immediately preceding program loop, and
the third condition is that a current number of program loops is equal to or greater than a first number.
