Abstract
A memory device and a control method for the memory device are provided. When it is determined that a bit read from a memory cell in a memory cell array is an erroneous bit, the memory device triggers a second reading cycle. During the second reading cycle, if the bit read from the same memory cell is still an erroneous bit, the memory cell is deemed to be a real defective memory cell. At this time, a repairing memory cell is selected from a repairing memory cell array to replace the real defective memory cell. The selected repairing memory cell and the real defective memory cell are coupled to the same word line.
