    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.

    摘要： A refresh address is generated with a refresh period for refreshing a memory device with refresh leveraging. A respective refresh is performed on a weak cell having a first address when the refresh address is a second address instead of on a first strong cell having the second address. A respective refresh is performed on one of the first strong cell or a second strong cell having a third address when the refresh address is the third address. Address information is stored for only one of the first, second, and third addresses such that memory capacity may be reduced. In alternative aspects, a respective refresh is performed on one of a weak cell, a first strong cell, or a second strong cell depending on a flag when the refresh address is any of at least one predetermined address to result in refresh leveraging.
