Abstract

A data output interface, in particular for semiconductor memories, provides a plurality of output drivers for providing data output signals in a manner dependent on a read command and a clock signal. In order to signal to a microprocessor that can be connected to the data output that data are provided, a data provision signal is additionally provided by a further output driver. The arrangement described can preferably be used for DDR-SDRAMs and enables particularly high clock frequencies.
