2. Figure 2 shows the block diagram of a 512 x 8 RAM chip. In this arrangement the memory chip is enabled only when CS1 is LOW and CS2 is HIGH. i How many bits can be stored in this memory chip? [2 marks] ii If a memory were constructed from the RAM in Figure 2, how many memory chips would be required to store a program of Ik bytes? [2 marks] iii If microprocessor 8085 have 16 address line, calculate the memory chip needed to support this microprocessor [2 marks] iv If the linear select decoding is used as chip select procedure, draw a truth table diagram of your implementation (Use linear decoding and don't care conditions) [6 Marks) Describe the disadvantages of the linear decoding and suggest on the solution.
