MEMORY DEVICE AND METHOD OF MANAGING MEMORY DATA ERROR

摘要

Memory devices and/or methods of managing memory data errors are provided. A memory device detects and corrects an error bit of data read from a plurality of memory cells, and identifies a memory cell storing the detected error bit. The memory device assigns a verification voltage to each of the plurality of first memory cells, the assigned verification voltage corresponding to the corrected bit for the identified memory cell, the assigned verification voltage corresponding to the read data for the remaining memory cells. The memory device readjusts the data stored in the plurality of memory cells using the assigned verification voltage. Through this, it is possible to increase a retention period of the data of the memory device.
