ABSTRACT:
A storage device which realizes fast access for data readout by use of a memory unit whose access time is relatively long. The device predicts a future address to be designated referencing a tendency of variation of addresses which were designated in the past. While the memory unit is not accessed from the outside such as from a central processing unit, data stored in a predicted address is read out to be stored in a registor. When a memory read command has arrived from the outside and if the predicted address coincides with a designated address, data in the predicted address is read out of the register which stores the data and delivered to an external data line.
