Abstract
Mémoire morte à dimension optimisée. La mémoire, ayant des lignes de mot métallique 28 et des lignes de bit diffusées 22, est adaptée pour avoir des dimensions optimales pour une performance et une capacité d'emmagasinage choisie. La longueur de la ligne de bit ou dimension Y peut être réduite de moitié lorsque la longueur de la ligne de mot ou dimension X est doublée. Alternativement, le rapport entre la dimension Y et la dimension X ou << rapport de configuration >> peut être changé pour une performance désirée a une capacité d'emmagasinage donnée. Peut être utilisé dans tout type de mémoire.
