Advanced keyword associative access memory system

摘要: Circuitry is disclosed which uses a rotating magnetic disc file as an associative access memory. Each block of data stored on the has associated with it keyword, keyword used to that particular data. The partitioned into angular sectors and blocks are in concentric, circular tracks one per sector track, having their keywords recorded radial preceding sector. Data requests, including information, request hopper all simultaneously compared each read from disc. When match occurs, track defined by matched during next order retrieve requested requests may alternatively specify address desired block.
