Abstract
The invention is a dynamic storage device requiring periodic refresh, and including logical operation circuitry within the refresh circuitry. The individual storage positions of the storage device are periodically read by a refresh amplifier, and then a logical operation is performed on the refresh data before application to the write amplifier. This allows implementation of associated data base searching by cyclically executing data compare and other logical operations within the refresh circuitry.
