Abstract
A semiconductor random access memory device having input terminals for receiving multi-bit data and output terminals for transmitting multi-bit data includes a memory cell matrix connected to a number of pairs of data lines and including a number of memory cells. Also included is an address decoder circuit which is responsive to an external address signal for providing address selection signals and a number of data input control circuits for receiving both 1-bit data signal and 1-bit signals of the multi-bit data and for providing as a pair of complementary signals either the 1-bit data signal or the one bit signal of the multi-bit data signal in response to various signals input thereto. A number of data input/output switching circuits and bit data output control circuits and 1-bit data output circuits and bit signal output control circuits are also provided for properly outputting either the 1-bit data or one bit signal of the multi-bit data from the output of the semiconductor random access memory device.
