Title (EN) MEMORY SYSTEM
(FR) SYSTEME DE MEMOIRE
Abstract: front page image
(EN)A memory system (10) having a word-addressable memory (12, 14) and bit changing circuitry (35) for changing or updating individual bits within the data words stored in the memory. The memory includes a primary memory (12) and a copy memory (14). The copy memory (14) stores duplicates of the data words stored in the primary memory (12). The bit changing circuitry (35) receives a word having a bit to be changed from the copy memory (14) and returns the word, including the changed bit, to both the primary memory (12) and copy memory (14). The memory system may constitute a parity memory system in a data processor.
(FR)Un systeme de memoire (10) ayant une memoire adressable par mots (12, 14) et un reseau de circuits de changement de bits (35) effectue le changement ou la mise a jour des bits individuels dans les mots de donnee stockes dans la memoire. La memoire comprend une memoire primaire (12) et une memoire de copie (14). La memoire de copie (14) emmagasine les doubles des mots de donnees emmagasines dans la memoire primaire (12). Le circuit de changement des bits (35) recoit un mot ayant un bit a changer provenant de la memoire de copie (14) et renvoie le mot, y compris le bit change, a la fois a la memoire primaire (12) et a la memoire de copie (14). Le systeme de memoire peut constituer un systeme de memoire de parite dans un processeur de donnees.
