Abstract
PURPOSE:To easily test a detecting and correcting cell such as a parity cell, etc., by providing a data transfer path establishing means, and establishing a data transfer path between the outside of a random access memory and the detecting and correcting cell based on control input from the outside. CONSTITUTION:A cell P for parity check is switched and connected to information data transfer paths 8a and 8b communicated to the outside of the random access memory by providing a data transfer path switching and connecting circuit 29. And the data transfer path is established between the cell P for parity check and the outside of the random access memory. Therefore, it is possible to perform the transfer of data between the outside by making access at random similarly as an information storing memory cell M. In such a way, it is possible to test the cell P for parity check with a simple procedure and in a short time.
