Abstract

A kind of semiconductor memory apparatus which can detect the dependence of input and output terminals on noise property of data output. The apparatus has the normal operation mode and the test mode. The apparatus is composed of a plurality of output buffers and the selector for at least one output buffer activated among the said a plurality of output buffers during the test mode.
