摘要
A memory device includes a memory cell array, a refresh controller, and control logic. The memory cell array includes a plurality of rows. The refresh controller performs a refresh operation on the plurality of rows. The control logic controls a care operation on a first adjacent region that is most adjacent to a first row based on a number of times the plurality of rows are accessed during a first period. The control logic also controls a care operation on a second adjacent region that is second adjacent to a second row based on a number of times the plurality of rows are accessed during a second period. The first and second periods are different periods.
