How many bits are used to address each chip in a memory that is 4G bytes large and made up of 128M by 1 byte memory chips? How many bits are used as the chip select in this memory?
-
How many bits are used to address each chip in a memory that is 64K bytes large and made up of 32K by 1 byte memory chips? How many bits are used as the chip select in this memory?

-
How many bits are used to address each chip in a memory that is 64K words large and made up of 128M by 1 byte memory chips? The word size is 8 bytes. How many bits are used as the chip select in this memory?
Detour Sign
In lecture, we discussed one possible method of creating a finite state machine for a detour sign. We are going to expand on this.
Instead of wrapping around from fully-lit to the all off state, the sign should reverse lighting direction until all lights are off. (see explanation on board)
