Large planes are getting away from massive lists of memory items on checklists. For a while at an old job we had no memory items, just "Fly the plane, silence the bell, read the checklist." (There were a couple steps to be accomplished by "immediate recall" for an aborted start and the F/E's whole purpose in life was to "protect essential.") On the 744 we have 5 checklists with memory items, the longest has 4 steps to done by memory, a couple just have one.
