SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PURPOSE: A semiconductor integrated circuit device with a power mesh structure is provided to secure data retention time by blocking the inflow of a noise in a memory cell block. CONSTITUTION: A cell block includes a plurality of cell mats including a plurality of bit lines and word lines. A cell plate electrode(150) is arranged on the upper side of the cell block. A plate power mesh line(160) is electrically connected to the cell plate electrode. The plate power mesh line includes a first plate power mesh line(160a) and a second plate power mesh line(160b). The first plate power mesh line is extended in parallel to the word line. The second plate power mesh line is extended in parallel to the bit line. The first plate power mesh line includes a cutting unit.
