    摘要: The memory device includes a memory array, control logic and a recovery circuit. The memory array has a first region configured to store data, a second region configured to store a portion of fail cell information, and a third region configured to store recovery information. The fail cell information identifies failed cells in the first region, and the recovery information is for recovering data stored in the identified failed cells. The control logic is configured to store the fail cell information, to transfer the portion of the fail cell information to the second region of the memory array, and to determine whether to perform a recovery operation based on address information in an access request and the portion of the fail cell information stored in the second region. The access request is a request to access the first region. The recovery circuit is configured to perform the recovery operation.

    摘要: A memory device includes a repair circuit including a fail bit location information table configured to store row and column addresses of a defective cell in a normal area of a memory cell array. The repair circuit also includes a row address comparison unit configured to compare the row address of the defective cell with a row address of a first access cell received from the outside, and to output a first row match signal when the defective cell's row address matches the row address of the first access cell, and a column address comparison unit configured to compare the column address of the defective cell with a column address of the first access cell received from the outside, and to output a first column address replacement signal if the column address of the defective cell is the same as the column address of the first access cell.
