Abstract
A semiconductor memory device changeable in word organization has a plurality of input/output terminals and a plurality of input terminals. Each of the plurality of input/output terminals and the plurality of input terminals are connected to an internal circuit via input/output buffers. These input/output buffers have identical structures and arrangements with identical input/output capacitance. The output buffer in the input/output buffer connected to an input terminal is coupled to a predetermined potential. The output buffer in the input/output buffer connected to an input/output terminal is activated by an output driver. The semiconductor memory device is generally set to a 1M word.times.1 bit organization. This semiconductor memory device may be set to a 256 k word.times.4 bit organization at the time of testing.
