I read the digital fundamentals book by thomas l floyd most parts. And I am again reading them. However I realized it lacks contents on memory(It has chapters but it is basic stuffs). It does not prepare you enough to take take a Computer Organization and Architecture class, where you will learn about designing control unit and stuffs like that.

Thus i am sitting in hackernews, asking about recommendations on what should be my next book?

Since I am interviewing for electronics companies soon, I will like to prepare myself for it as well.
