How to design a Design a 32 x 4 memory using two 16 x 4 RAM chips


I have this task to "Design a 32 x 4 memory using two 16 x 4 chips". But on Google I can't find what a 16 x 4 RAM is. I know the basics of latch, flip-flops, TTL, CMOS etc. But I can't put this together. Where do I start?



Answer
