Thus information is transferred in parallel in a broad band path depending upon the size of the photoresponsive cell array, hologram efficiency, etc. During a succeeding machine cycle, the entire contents of the associative or functional storage unit may be searched in accordance with a search argument to select from the storage unit data which corresponds to the search argument. In this fashion, significant quantities of data are searched rapidly. Within the same system, the holographic array can be controlled during one machine cycle to change the entire contents of additional storage arrays which may be of the associative, functional or location addressable type. In this fashion, storage units such as microprogram control stores, operating system program stores and user application program stores can be rapidly changed, for example, a page (e.g., 2000 bytes) at a time during one machine cycle. This adds a new dimension for information transfer within high performance data processing systems. In one embodiment, read/write hologram arrays, the contents of which are selectively changeable, are utilized to provide a greater versatility and performance to system operation.，下面是Processor utilizing one holographic array and a plurality of photoresponsive storage arrays for high paging performance专利的具体信息内容。
