Abstract
A memory device, a memory system and a control method thereof to identify a programming state of memory cells includes an example memory device with a memory block including a plurality of memory cells; a plurality of word lines coupled to the memory block; and a peripheral circuit coupled to the plurality of word lines and configured to: perform a first programming operation in response to a first operation command to program first memory cells; perform a first verification operation to obtain the first number of second memory cells that are coupled to the first word line, have an erased state as the target state and have a threshold voltage larger than a first verification voltage, which is a verification voltage of the first programmed state; and generate a first state identifier indicating a programming failure in response to the first number being larger than a first threshold.
