Abstract

An output driver circuit of a clocked integrated semiconductor memory of the DRAM type is driven by a circuit for generating an output signal as a function of two input signals. A validity signal, which is supplied to the circuit, ensures that the data to be output are in a valid state before the output driver is activated. As a result, a situation in which different propagation times of input signals of the output driver circuit lead to multiple switching operations within an access cycle of a memory access is prevented. An event-oriented control of the enabling process of the output driver ensures a proper function even in the case of variable frequencies of the clock control.
