Associative memory

Abstract

Abstract AN ASSOCIATIVE MEMORY IS DISCLOSED COMPOSED OF MODULES EACH HAVING A PLURALITY OF STORAGE CELLS SELECTIVELY OPERABLE AS DATA BIT CELLS OR ASSOCIATIVE SEARCH BIT CELLS. THE ASSOCIATIVE MEMORY IS ORGANIZED IN ROWS AND COLUMNS. THE CELLS ON EACH COLUMN ARE CONNECTED TO A DATA RECORD CONTROL LINE BEING RAISED, IF THE BIT IN THE ACCOMPANYING BIT VALUE LINE IS TO BE RECORDED IN A CELL ON THE COLUMN. A THIRD LINE OF THE COLUMN IS A SEARCH SELECT LINE TO IDENTIFY A BIT IN THE BIT VALUE LINE AS SEARCH CRITERION. CELLS IN A ROW ARE CONNECTED TO A LINE WHICH PROVIDES AN ENABLING SIGNAL IF ALL CELLS ON COLUMNS, WHOSE SEARCH LINE HAVE BEEN RAISED, HOLD BITS WHICH AGREE WITH THE BITS IN TEH CORRESPONDING BIT VALUE LINE, OR HAVE BEEN EXTERNALLY ADDRESSED. A PRIORITY SYSTEM AMONG THSES ROW LINES INHIBITS MULTIPLE WORD ADDRESSING. DATA ARE TAKEN FROM OUTPUT LINES ALONG THE COLUMNS.
