Abstract:
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.

Claim (Index 12):
A method for operating a memory device, including a memory cell array which includes a plurality of rows and first to nth adjacent regions (where n is an integer equal to or more than two) that are based on a degree of adjacency to a first row, the method comprising:\n performing a counting operation on number of accesses of the plurality of rows to determine an intensively accessed row; selecting one adjacent region from among the first to nth adjacent regions based on a condition of performing the counting operation; and performing a care refresh operation on one or more rows in the selected one adjacent region.
