Abstract

Disclosed is a nonvolatile memory device which includes a memory cell array, a row decoder circuit that selects one wordline as a target of a program operation, a page buffer circuit that stores data to be written in memory cells connected with the selected wordline in the program operation, and a pass/fail check circuit that determines a pass or a fail of the program operation. In the program operation, the pass/fail check circuit detects a first program speed of first memory cells and a second program speed of second memory cells, and determines a program fail based on the first program speed and the second program speed.
