Abstract

An associative main store, having application in computing technology and automation, avoids disadvantages of well-known associative main stores which have a great number of external outputs due to the presence of inputs to address every memory cell, and which require that the addresses be stored in an extra external device. The invention is able to increase the digits of the associative conditions facilitating operation by the user and providing extended functional possibilities. Instead of having only one associative function: 'associative YES/NO reading' the invention has four new associative functions in addition: 'multiple response' where all numbers written in the associative main store equivalent to the preset masked input information are read; 'all numbers smaller than a preset number' where all numbers written in the associative main store being smaller than a given input information are read; 'all numbers bigger than a preset number' where all numbers written in the operative storage bigger than the preset input information are read; and 'all numbers in the FROM/TO interval' where all numbers written in the associative main store entering a preset interval or being outside a preset interval are read. Bidirectional input-output data buses are used in order to avoid any considerable increase in the number of the device outputs.
