ABSTRACT:
A sense amplifier is provided with a trimming capability to provide a semiconductor memory device capable of a reading operation at higher speeds than related-art technology. A trimming means (8) is provided for controlling a trimming block (7) in a sense amplifier (5) to perform a trimming operation. A fuse is used for the trimming means (8). The fuse is cut at a necessary position at any given time after fabrication, thereby allowing initialization for reducing the input offset of the sense amplifier (5).
