  • Semiconductor memory device with redundant row substitution architecture and a method of driving a row thereof
    Patent number: 6201745
    Abstract: A semiconductor memory device has a sub word line driver structure and includes a main word line decoder driver, an address programming circuit, and a redundant main word line decoder driver. When row address bit signals are input, the main word line decoder driver drives a main word line corresponding to the row address bit signals regardless of a row replacement with redundant rows. If the row address bit signals correspond to programmed defective row address bit signals, the address programming circuit generates a redundant row select signal, in response to which the activated main word line is deactivated and a redundant main word line is activated. According to the redundant row replacement scheme of the present invention, access time is reduced without an increase of a layout area.
