  • Patent number: 11676674
    Abstract: A memory device includes a cell group including a plurality of non-volatile memory cells capable of storing data and a control circuit configured to perform plural program loops for storing the data, each program loop including a program voltage application operation and a verification operation. During the respective program loop, the control circuit performs the verification operation for an N target level, an N?1 target level lower than the N target level, and an N+1 higher than the N target level, in response to the program voltage application operation for the N target level. When a quantity of non-volatile memory cells having threshold voltages over the N+1 target level satisfies a preset criterion, the control circuit skips a next verification for a target level lower than the N+1 target level, in response to a next program voltage application operation for the N+1 target level.
