Abstract

A MEMORY SYSTEM INCLUDES AT LEAST ONE OR MORE MEMORY MODULE BOARDS IDENTICAL IN CONSTRUCTION AND A SINGLE COMPUTER BOARD CONTAINING THE CONTROL CIRCUITS FOR CONTROLLING MEMORY OPERATIONS. EACH BOARD PLUGS INTO THE MAIN BOARD AND INCLUDES A MEMORY SECTION HAVING A NUMBER OF ROWS OF MEMORY CHIPS AND AN IDENTIFICATION SECTION CONTAINING CIRCUIT FOR GENERATING SIGNALS INDICATING THE BOARD DENSITY AND THE TYPE OF MEMORY PARTS USED IN CONSTRUCTING THE BOARD'S MEMORY SECTION. THE MAIN BOARD CONTROL CIRCUITS INCLUDE A NUMBER OF DECODER CIRCUITS WHICH COUPLE TO THE IDENTIFICATION AND TO THE MEMORY SECTION OF EACH MEMORY MODULE BOARD. THE DECODER CIRCUITS RECEIVE DIFFERENT ADDRESS BIT COMBINATIONS OF A PREDETERMINED MULTIBIT ADDRESS PORTION OF EACH MEMORY REQUEST ADDRESS. IN RESPONSE TO SIGNALS GENERATED BY THE IDENTIFICATION SECTIONS OF THE INSTALLED MEMORY BOARDS, THE DECODER CIRCUITS ARE SELECTIVELY ENABLE TO DECODE THOSE BIT COMBINATIONS OF THE ADDRESS PORTION SPECIFIED BY THE SECTIONS FORENABLING SUCCESSIVE ADDRESSING OF ALL OF THE BLOCKS OF LOCATION WITHIN THE SYSTEM.
