Abstract

A memory device includes a memory cell array, a row select circuit, a refresh controller and a memory control logic. The memory cell array includes memory cells arranged in rows and columns. The row select circuit is connected to the rows. The refresh controller controls the row select circuit to apply a refresh operating voltage to one or more rows. The memory control logic decodes a command received from a memory controller and outputs a refresh command and external refresh address information. The refresh controller controls the row select circuit to perform one of an external refresh operation and an internal refresh operation, based on the refresh command that is output from the memory controller and based on whether a first row-hammering row address of the internal refresh operation is identical with a second row-hammering row address of the external refresh operation.
