ABSTRACT:
It is an object of the invention to provide a semiconductor memory integrated circuit wherein the sate of all of the memory cells in the memory array can be checked by measuring only one data output terminal. A means for interconnecting read signal buses is provided to connect the read signal buses to each other. A multiplicity of IC chips can be simultaneously measured and inspected even if the numbers of the drivers, comparators and DC measuring units, and the like available in the inspection apparatus used are limited.
