I would say CS is probably the least focused degree on memorization one can find at most schools. Compared to the Pharmacy and Accounting degrees my siblings obtained, I barely had to memorize anything at all (at least for courses in CS/CS&E department). I did my undergrad at Ohio State and many tests were open book (or some notes allowed).

Material you were tested on was generally what you did on your labs, so if you did well on the labs, then the test wasn't an issue. I never had a professor require memorizing syntactical things, such as names of functions in a particular language. If we needed to write code a test, a reference sheet was provided for functions/collections and the parameters they took.
