摘要:
The data output circuit for a semiconductor memory apparatus includes a first control signal generating unit configured to generate a first control signal according to a row address and a read command; and a data selecting unit configured to select data from a data line corresponding to a presently selected unit data output mode among data lines according to the first control signal or a second control signal, and output the data.
