Abstract
The present invention discloses a semiconductor memory device having an NK refresh cycle, which can lower an enable speed of a word line by reducing a resistance and a capacitance of the word line enabled during an access operation by using a redundant row address. When the,NK and NK refresh operations are simultaneously embodied, the read/write operation is carried out by using an address compressed in the device set up by the NK refresh operation. As a result, as compared with the,NK refresh operation, a length of the word line to be enabled is reduced to a half, and the number of the cells connected to the word line is also decreased, thereby remarkably improving the speed at the row path side.
