Abstract
A semiconductor device having an SRAM which includes: a monolithic first active region in which a first transistor and a fifth transistor are disposed; a second active region separated from the first active region, in which a second transistor is disposed; a monolithic third active region in which a third transistor and a sixth transistor are disposed; and a fourth active region separated from the third active region, in which a fourth transistor is disposed. Each driver transistor is divided into a first transistor and a second transistor (or a third transistor and a fourth transistor) and these driver transistors are disposed over different active regions.
