Abstract
A memory device includes a memory bank, a row selection circuit and a refresh controller. The memory bank includes a plurality of memory blocks, and each memory block includes a plurality of memory cells arranged in rows and columns. The row selection circuit performs an access operation with respect to the memory bank and a hammer refresh operation with respect to a row that is physically adjacent to a row that is accessed intensively. The refresh controller controls the row selection circuit such that the hammer refresh operation is performed during a row active time for the access operation. The hammer refresh operation may be performed efficiently and performance of the memory device may be enhanced by performing the hammer refresh operation during the row active time for the access operation.
