“We don't need no education”
You don't need no memory.
Just don't know what it means.
In standard English, when you turn a sentence like "I have some memory" into a question or a negative statement, you normally replace "some" by the special word "any": "I haven't any memory"/ "Have you any memory?".
Linguists call this "any" a "negative polarity" word, because it is particularly associated with negative sentences (and also questions): you can't use it in affirmative sentences, at least not with that meaning.
Many dialects of English replace this particular negative polarity word "any" with a different one "no". This form is generally strongly deprecated by authorities and pedants, and they frequently adduce a pseudo-logical argument about double negatives.
It's very informal, possibly even slang (?) and means "You don't need (any) memory".
