  • System for arranging and sharing shift register memory
    Patent number: 4078258
    Abstract: A system for arranging the memory in an electronic dynamic shift register for performing multiple operations during a memory revolution. Control codes, such as separator and record flags, are input into the shift register memory for defining an input and a revision zone. Upon detecting these control codes during a memory revolution, data codes are input into the input and revision zones and deleted from the revision zone. Another control code, such as a page end code, input into the revision zone defines an output zone. During an output operation data codes in the output zone are output from the record flag through the page end code.
