Abstract
A semiconductor memory device, in which in each unit circuit of a data output circuit, a resistor is connected to an input terminal of an inverter for performing a buffering amplification, and a transfer gate is turned on (closed) to short-circuit both ends of the resistor so as to pass corrected data output from an error correction circuit not via the resistor but directly to the inverter when a bit corresponding to an error check signal output from an error check circuit has an active level, resulting in a reduced time for outputting the corrected data.
