Abstract
A nonvolatile memory device includes a memory cell array comprising memory cells connected to bit lines and word lines; a word line decoder configured to apply word line voltages to the word lines; a bit line selector configured to select at least one bit line of the bit lines; a control logic configured to control the word line decoder and the bit line selector so that write data is programmed in the memory cell array; and a sudden power off (SPO) detection circuit, wherein the SPO detection circuit comprises: a sensing cell; a first driver configured to provide a first voltage to the sensing cell; and a second driver configured to provide a second voltage to the sensing cell, wherein a program state of the sensing cell becomes different depending on an order or a time difference between the first driver and the second driver being powered off.
