If a memory chip has 13 address pins (A0..A12), then it has:
213 = 23 X 210 = 8K locations.
If a memory chip has 4K locations, then it should have N pins:
2N = 4K = 22 X 210 = 212 → N=12 address pins (A0..A11)
213 = 23 X 210 = 8K locations.
If a memory chip has 4K locations, then it should have N pins:
2N = 4K = 22 X 210 = 212 → N=12 address pins (A0..A11)
