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?
As this sounds like a homework question I'll give you something to start your answer.
32 x 4 means 32 unique addresses (that is 5 bit address) with a 4 bit data lines. Similarly 16 x 4 would be 16 unique addresses (that is 4 bit address) with 4 bit data lines.
