Abstract
A semiconductor memory has a recognition circuit for signal changes which deactivates a pre-loading circuit. The pre-loading circuit charges the data lines upon appearance of an address signal change, and then reactivates them again in time-delayed fashion. A clock voltage generator is provided which generates a clock voltage that activates the pre-loading circuit and, given the appearance of an address signal change, switches the clock voltage to a first level that deactivates the pre-loading circuit and, given the appearance of an output signal at the read amplifier, switches this clock voltage to a second level activating the pre-loading circuit.
