Abstract

The semiconductor store has at least one storage matrix, using dynamic storage elements, for storing binary data, an address coder, for addressing and writing in the data, a read-out device for retrieving the stored data and regenerating means, operated by a release signal, to regenerate the stored data. A circuit element (1) has an output supplying a reference voltage representing the decay of the stored data, to a threshold circuit (3), which provides a release signal for the regeneration means when the reference voltage reaches a critical value. A setting device (2) for the circuit element (1) also operates in response to the release signal.
