Title (EN) MEMORY ARRAY HAVING IMPROVED ISOLATION BETWEEN SENSE LINES
(FR) RESEAU DE MEMOIRE AYANT UNE ISOLATION AMELIOREE ENTRE LES LIGNES DE LECTURE
Abstract: front page image
(EN)A memory array having improved isolation between the bit sense common lines (22, 23, 26, 27) is provided by using diode connected transistors (40-43). The diode connected transistors (40-43) substantially eliminate any current flow between bit sense common lines (22, 23, 26, 27) when a certain portion of the column select circuitry has not been selected. Since the blocking transistors (40-43) prevent current flow there is no noise generated to be coupled to one of the control lines (28). This results in a memory array which can operate at higher speeds since better differential signals are established to be sensed by the sense amplifier.
(FR)Un reseau de memoire ayant une isolation amelioree entre les lignes communes de lecture de bits (22, 23, 26, 27) utilise des transistors connectes par des diodes (40-43). Les transistors a diodes de connexion (40-43) eliminent sensiblement tout courant passant entre les lignes communes de detection de bits (22, 23, 26, 27) lorsqu'une certaine partie du reseau de circuit d'une colonne n'a pas ete selectionnee. Etant donne que les transistors de blocage (40-43) empechent le courant de passer, cela elimine les bruits d'accouplement sur l'une des lignes de commande (28). Ceci permet d'obtenir un reseau de memoire qui peut fonctionner a des vitesses superieures etant donne que de meilleurs signaux differentiels peuvent etre etablis, lesquels sont detectes par l'amplificateur de detection.
