Abstract
Abstract A memory system for simultaneously accessing a memory from a large number of sources includes a cyclic memory from which stored information is continuously read by a plurality of read means and temporarily entered into comparison registers, input registers receive and temporarily store at least one of the coded digits on said memory, and comparators generate a signal upon the existence of a coincidence between a coded digit momentarily in said comparator register and a coded digit temporarily stored in said input register. The existence of such coincidence is used to trigger arithmetic and logic units for further processing of the information.
