    摘要: A memory device comprises a memory cell array and a bad page map. The memory cell array comprises a plurality of memory cells arranged in pages and columns, wherein the memory cell array is divided into a first memory block and a second memory block each corresponding to an array of the memory cells. The bad page map stores bad page location information indicating whether each of the pages of the first memory block is good or bad. A fail page address of the first memory block is replaced by a pass page address of the second memory block according to the bad page location information.
