Question

Assume it is decided to design a two dimensional 512 byte (byte addressable) RAM from 16 byte chips. Each of the 16 byte chips has two select-lines. The chip is enabled only if both of the select-lines are activated. Your design must use only decoders of size 3 X 8 and 2 X 4. Need to show the components, the connections and size of each component!
