Abstract
A semiconductor device includes a memory cell array, in which bit lines intersect word lines to form a memory cell. Representative pads are selected from among pads. Data input to the representative pads is decompressed to data corresponding to all of the pads, and is written in corresponding memory cells. The data is read and divided into number of groups corresponding to number of the representative pads. It is determined whether the data in each group coincide with the data input to the representative pads. Output to the representative pads is controlled based on a result of the determination.
