ABRASION LEVELING METHOD OF A NON-VOLATILE MEMORY DEVICE FOR EFFECTIVE ABRASION LEVELING BETWEEN A SINGLE LEVEL MEMORY CELL BLOCK AND A MULTI-LEVEL MEMORY CELL BLOCK

摘要

PURPOSE: An abrasion leveling method of a non-volatile memory device for effective abrasion leveling between a single level memory cell block and a multi-level memory cell block is provided to implement an abrasion leveling between a single level memory cell block and a multi level memory cell block by changing the block consistency of logic block address.;CONSTITUTION: An average erasing frequency is calculated by obtaining respective erasing frequencies of a memory cell blocks of a non-volatile memory device(41). A program erasing frequency of the single level memory cell block is calculated(42). A converted program erasing frequency of the multi-level memory cell block is calculated(43).;COPYRIGHT KIPO 2010
