Comparaison entre un module de mémoire SDRAM et un EDO (en bas)
L'EDO ou Extended Data Out (« sortie des données améliorée ») est un format de mémoire vive (aujourd'hui dépassé pour la majorité des micro-ordinateurs).
La RAM EDO est apparue en 1995 (génération 386/486/Pentium). Caractérisée par la présence d'un petit tampon de mémoire cache, la mémoire EDO était 15 % plus rapide que la mémoire FPM qu'elle avait remplacée. Elle se présentait sous forme de barrettes DIMM de 30 ou 72 broches, et 144 broches en SO-DIMM (pour ordinateurs portables). Les fréquences disponibles étaient de 33 et 66 MHz. Mais comme elle n'acceptait pas des fréquences supérieures, elle a ensuite disparue au bénéfice de la SDRAM (vers 1997, génération Pentium II).
