Abstract

PURPOSE:To reduce current consumption and to conduct an interference test by operating m bits on a separate memory cell plate at the same time in a semiconductor storage device of n-wordX1-bit constitution to conduct n/m- wordXm-bit test (where n is a multiple of m). CONSTITUTION:Any of data amplifiers 4-7 is selected via an address buffer circuit 29 at the normal operation to operate memory cell arrays 8-11 corresponding to n=4-wordX1-bit constitution. Thus, the current consumption by undesired amplifiers 4-7 is not required and the current consumption is reduced. At the time of test mode, on the other hand, the m=1 bit of separate arrays 8-11 is operated at the same time and the test of n/m=4-wordXm=1-bit constitution is conducted and the interference test among the arrays 8-11 is conducted.
