Abstract
A secondary storage facility that connects to a digital data processing system. The system includes a central processor, an associative memory and a random access memory connected to the associative memory. The secondary storage facility includes a controller and one or more direct access secondary storage units. A first bus connector interconnects the controller to a first bus from the central processor and transfers of control information are routed over this bus. The controller also connects to the associative memory so that data, together with address and control information, is routed between the random access memory and a storage unit through this second connection.
