i like the memory concept per se (vancian magic systems i like a lot). i dont like the cost-system, though. it does not add something valuable. its a rather boring "spell shop system" with fixed cost per spell.
id rather have something like: 1:1 basic cost for all spells but the more slots you use for one spell the more powerful that spell becomes (like 1 slot fireball does x damage, 2 slot fireball does x+y damage, up to a limit of "spendable" slots course)
and points spent in skill trees add one or more special effects to the spells of that school (more effects the more points spent, could be quite costly to balance the effects, eg cool down reduction or life leech (like as of now in necromancy) or something else)
