First I really don't know where I should post this (I'm assuming this place is fine, maybe coursework?) So I built a circuit that includes a 1k x 4 RAM ( so I'm assuming that stands for 4000 Kb but I wouldn't see why you'd need to write 1k x 4 RAM) Furthermore, I'm having trouble understanding how my decoder works. I used a 4-to-10 decoder and that means that there are only a possible of 10 outputs. That makes sense to me as there are only 10 pins. However, my ram can contain much more information then that, so why wouldn't I be able to do ( with my decoder) 10 inputs of all 1 and one 0. And then the inverse. Thanks for the help!
