Semiconductor memory device and method for operating the same

Abstract

Provided herein may be a semiconductor memory device and a method for operating the same. The semiconductor memory device may include a memory cell array, a peripheral circuit, control logic, a status storage unit, and an operating characteristic checking unit. The memory cell array may include memory cells. The peripheral circuit may perform an operation for writing data to the memory cell array, reading data from the memory cell array, or erasing data written to the memory cell array. The control logic may control the peripheral circuit so that a data write operation, a data read operation or a data erase operation is performed. The status storage unit may store an operational status of the memory cell array as a first status value. The operating characteristic checking unit may receive an operating characteristic value, and generate a second status value via a comparison with an operation threshold value.
