    摘要: A semiconductor memory having an error correcting function is provided, which has a device by which the user finds no difficulty in making use of the semiconductor memory and can test it with ease. In the semiconductor memory, a signal indicative of the completion of the preparation for reading/writing is outputted from the memory so that the user, after detecting the output of this signal, performs reading/writing data. To facilitate tests, such as a memory cell test for a redundant bit (check bit), an encoding circuit test and a decoding circuit test, the present invention provides that the arranged tests can be made independently of each other.

    摘要: An address multiplexed dynamic random access memory (RAM) which has both a normal operation mode and a test mode capability is provided. The test mode is initiated in response to particular signal level combinations of both the row address strobe (RAS) and column address strobe (CAS) signals and the write enable (WE) signal. Since the signal level combinations employed in connection with implementing the test mode are unused in the normal operating mode of the dynamic RAM, additional external terminals are unneeded. This dynamic RAM employs multiplexing circuitry on both the input side as well as on the output side of the dynamic RAM, which multiplexing circuitry is controlled during normal operation by select signals from a decoder and during the test mode by a test signal which allows accessing of data at all of the common complementary data lines by the testing circuitry so as to determine whether there is consistency or inconsistency of the data being read out for testing.
