摘要
PURPOSE: A memory system and a bad block management method thereof are provided to improve the efficiency of a memory block.;CONSTITUTION: A first step is processed to determine that a memory block satisfies a bad block condition(S110). When the memory block satisfies the bad block condition, a subsequent treatment operates in the memory block(S120). The memory block is allocated to the bad block(S130). When the bad block satisfies a bad block release condition, the bad block is released. The subsequent treatment programs a cell in the erase state into a program state cell or stores the timing to assign the memory block as the bad block.;COPYRIGHT KIPO 2011
