摘要: Provided herein may be a memory device, a memory system having the memory device, and a method of operating the memory device. The memory device may include a memory cell array configured to store data, a peripheral circuit configured to perform a program operation on the memory cell array, and a control logic configured to perform the program operation by controlling the peripheral circuit and to perform a status check operation after the program operation. Here, the control logic may be configured to, based on a determination that the status check operation has passed, perform a number-of-program pulses comparison operation by comparing a number of program pulses used in the program operation to a first preset range.
