<p>The invention is a dynamic storage device (Figs. 3-10) requiring periodic refresh, and including logical operation circuitry (e.g., 21 and 24 of Fig.4) within the refresh circuitry (19 of Fig. 4). The individual storage positions of the storage device are periodically read by a refresh amplifier (RE of Fig. 4), and then a logical operation is performed on the refresh data before the data is applied to the write amplifier (WR of Fig. 4). This operation allows implementation of associative data base searching by cyclically executing data compare and other logical operations within the refresh circuitry. Storage systems for use with such devices (e.g., Fig. 12) are also disclosed.</p> |
