Semiconductor device

Abstract

A semiconductor device is provided that operates at improved write speeds without an increase in area. The semiconductor device according to the invention includes a plurality of memory cells arranged in a matrix of rows and columns, a plurality of word lines provided to each row of the memory cells, a plurality of bit line pairs provided to each column of the memory cells, sense amplifiers that amplify the potential difference in the bit line pairs, data line pairs that transfer data to the bit line pairs, column selection circuits that permit receiving the data from the data line pairs, a column decoder that transmits column selection signals to the column selection circuits, and a sense amplifier control circuit that activates the sense amplifiers after the column decoder transmits the column selection signals to the column selection circuits.
