MEMORY DEVICE, MEMORY SYSTEM, METHOD OF OPERATING A MEMORY DEVICE, AND METHOD OF OPERATING A MEMORY SYSTEM

摘要

A method is for operating a memory system including a memory device. The method includes managing program order information of the memory device based on a program order stamp (POS) indicating a relative temporal relationship between program operations of a plurality of memory groups that are included in the memory device, and controlling a read voltage for performing a read operation on the memory device. The read voltage is controlled based on the program order information and a mapping table that stores a read voltage offset and a POS corresponding to the read voltage offset.

1. A method of operating a memory system comprising a memory device, the method comprising:
managing program order information of the memory device based on a program order stamp (POS) indicating a relative temporal relationship between program operations of a plurality of memory groups that are included in the memory device; and controlling a read voltage for performing a read operation on the memory device, based on the program order information and a mapping table that stores a read voltage offset and a POS corresponding to the read voltage offset.
