ABSTRACT:
A semiconductor memory device and a column decoder thereof, in which data is masked using column select line signals obtained by the combination of masking signals and a column address to control the column select line signals and reduce the number of data input/output lines and the number of data input/output drivers. The semiconductor memory device includes: a plurality of memory cell arrays including a plurality of memory cells connected between word lines and bit lines; a plurality of switches each having one end connected to that of an adjacent a first memory cell array, and the other end connected to the bit line of a second memory cell array, which turn on in response to column select line signals, with the column select line signals obtained by combination of masking signals, such that data is not written to a column address and the bit line corresponding to the column address; one or more data input/output drivers for bidirectionally driving the data; and data input/output lines for connecting the output of each of the data input/output drivers to the bit lines.
