Abstract
An information storage controller comprises two memory groups. One memory group is used for external communication, while the other memory group communicates with a plurality of magnetic disks, so that work in each memory group is performed in parallel. Information is transmitted between the external equipment and the magnetic disk by a switch means. Further, the information storage controller comprises a redundant information generation circuit for reading information from a plurality of memories with an exclusive circuit which simultaneously generates redundant information and verifies and recovers data. Thus, a high speed information storage controller connected to a plurality of magnetic disks can be provided.
