The problem with "memoize" is people always think I'm trying to say "memorize" with a speech impediment, especially because both words usually (kind of) make sense in the context.
Also, some spellcheckers will surreptitiously auto-"correct" memoization to "memorization" (as, e.g. Word, and I happen to know it does that because it did it in my Master's dissertation; luckily, just a footnote but probably made me look like an idiot trying to show off with terms I don't understand).
