MEMORY HAVING NON-FIXED RELATIONSHIPS BETWEEN ADDRESSES AND STORAGE LOCATIONS

摘要

There is disclosed a memory in which there are no fixed relationships between received addresses and storage locations. In some modes of operation, fixed relationships may be established and maintained, but subsequently changed. In other modes of operation, the receipt of the same address in successive memory cycles controls access to different sequential storage locations. In such modes of operation, some of the bits treated by the CPU as address bits are actually interpreted as representing instruction codes. When the memory is operated in one of the latter modes, long messages may be stored in buffer areas of the storage while "using up" only a greatly reduced area of the computer address space.
