Abstract
A semiconductor memory device reduces the distance occupied between a data path circuit and pads, and minimizes the length of data lines and main input/output lines, thereby improving an operating speed thereof. The semiconductor memory device includes a memory array divided into four array blocks which are independently arranged; a plurality of pads disposed in an area between the upper array blocks and the respective lower array blocks; a data path control circuit disposed in an area between the left array blocks and the respective right array blocks; a data path circuit disposed in a middle center area among the four array blocks; a plurality of data lines connecting the pads to the data path circuit; and a plurality of main input/output lines connecting the memory array to the data path circuit. In this configuration, a distance between the data lines and the main input/output lines and the data path circuit can be minimized.
