Nonvolatile memory device detecting power noise and operating method thereof

Abstract

A nonvolatile memory device includes a memory cell array that stores data, and control logic. The control logic is configured to control a read operation, a program operation, or an erase operation on the data. The control logic is configured to detect a first power noise based on one of voltage sources to be provided to the memory cell array and a first reference voltage and detect a second power noise based on the one voltage source of the voltage sources and each of the first reference voltage and a second reference voltage. The control logic is configured to determine whether to perform at least one of an operation period of the read operation, an operation period of the program operation, or an operation period of the erase operation, based on whether at least one of the first and second power noises is detected.
