Abstract

A semiconductor device includes two sense amplifiers provided on a semiconductor substrate. Each of two sense amplifiers is formed of a pair of transistors. Two transistors are separated from each other by an element-isolating insulating portion provided on the semiconductor substrate. Therefore unlike the conventional, two transistors do not share the source region with each other, resulting in a semiconductor device with an improved sensitivity of a sense amplifier.
