Abstract

A semiconductor device includes a first CMOS inverter, a second CMOS inverter, a first transfer transistor and a second transfer transistor wherein the first and second transfer transistors are formed respectively in first and second device regions defined on a semiconductor device by a device isolation region so as to extend in parallel with each other, the first transfer transistor contacting with a first bit line at a first bit contact region on the first device region, the second transfer transistor contacting with a second bit line at a second bit contact region on the second device region, wherein the first bit contact region is formed in the first device region such that a center of said the bit contact region is offset toward the second device region, and wherein the second bit contact region is formed in the second device region such that a center of the second bit contact region is offset toward the first device region.
