is there a correlation btwn working memory and iq?

Answer 1

I think of them as two different things.

Working memory is just a storage area for facts.

Intelligence is the ability to apply logic and analytical skills to solving a problem.

You need some knowledge to be effective, but, in many cases, if one only has a general perception of the problem, he can come up with a unique solution.

However, your basic premise is correct. There is a high correlation between the two.
