Abstract
Provided herein is a memory device and a method of operating the same. The memory device includes memory cells coupled between a word line and bit lines, a main processor configured to control program-related voltages that are applied to the word line and the bit lines, a page buffer configured to store data sensed based on threshold voltages of the memory cells, a sensing circuit configured to perform a pass/fail check operation of comparing a sensing current corresponding to the sensed data with a reference current, and a sub-processor configured to control the page buffer and the sensing circuit to perform the pass/fail check operation in parallel with control of the program-related voltages while the main processor controls the program-related voltages.
