ABSTRACT:
A semiconductor memory device is disclosed in which an output data voltage of a sense amplifier is compared with a reference voltage to produce an output data corresponding to the data stored in the selected memory cell. The reference voltage is generated in response to a current flowing through a dummy memory transistor having the same device structure as a memory transistor and is thus variable if the current flowing through the memory transistor is deviated from the designed value.
