Title (EN) FLASH DEVICEWITH SHARED WORD LINES AND MANUFACTURING METHODS THEREOF
(FR) MEMOIRES FLASH A LIGNES DE MOTS PARTAGEES
Abstract: front page image
(EN)Word lines of a NAND flash memory array are formed by concentric, rectangular shaped, closed loops that have a width of approximately half the minimum feature size of the patterning process used. The resulting circuits have word lines linked together so that peripheral circuits are shared. Separate erase blocks are established by shield plates.
(FR)Les lignes de mots d'un réseau de mémoire flash NON-ET sont formées par des boucles fermées concentriques et rectangulaires ayant une largeur sensiblement de la moitié de la taille du trait minimum du procédé de création de motifs. Les circuits résultants comportent des lignes de mots reliées entre elles de manière à partager les circuits périphériques. Des blocs effaçage séparés sont délimités par des plaques de blindage.
