Abstract: A semiconductor device including memory cell transistors on a substrate is provided. The semiconductor device includes a first wiring layer on the memory cell transistors and including a bit line and a first conductive pattern, a second wiring layer on the first wiring layer and including a ground line, a first via interposed between and electrically connecting the bit line and a source/drain of a first memory cell transistor among the memory cell transistors, and a first extended via interposed between the ground line and a source/drain of a second memory cell transistor among the memory cell transistors. The ground line is electrically connected to the source/drain of the second memory cell transistor through the first extended via and the first conductive pattern. The first extended via has a width greater than that of the first via.

Abstract: Disclosed is a static random access memory (SRAM) device. According to example embodiments of the present disclosure, a control logic of the SRAM device may include a tracking circuit connected with metal lines for tracking the number of columns of a memory cell array and the number of rows of the memory cell array. By the tracking circuit, a length of word lines of the memory cell array and a length of bit lines of the memory cell array may be tracked. The control logic of the SRAM device may generate control pulses optimized for the size of the memory cell array, based on a tracking result(s) of the tracking circuit. Accordingly, a power and a time necessary for a write operation and a read operation may be reduced.
