Conceptually 'Memory' sounds more like 'Preparation'. As in the player character prepares certain skills/spells for the next encounter rather than say memorises certain skills/spells. Makes more sense to me. Memorising implies that the PC forgets things habitually whereas preparation implies planning for the next encounter.
If you don't like the sound of Preparation you can call it Planning or a synonym of it that sounds cooler.
synonyms: arrangements, planning, plans, provision, preparatory measures, preliminaries, necessary steps, groundwork, spadework, foundation, gearing up
"preparations for the conference will begin almost immediately"
