Abstract

There is provided a semiconductor memory device having a multibank in which a single large memory cell is divided into a plurality of banks without increasing power consumption and chip size. In the semiconductor memory device, a memory cell array is divided into a plurality of banks arranged alternately, and each bank includes a plurality of unit memory cell arrays. In addition, column selection lines of each bank are connected to alternate output ports of a column decoder, and the column decoder enables the column selection lines of a bank selected from the plurality of banks in response to address decoding signals and bank selection signals.
