(c) With the help of a fully labeled diagram, distinguish between direct and related mapping in cache memory?
(d) One example of a semiconductor memory is the DRAM
(i) Describe why a 16 Mbit DRAM chip is better being organised as compared a (2048 x 2048) x 4-bit array instead of 1M of 16 bit words.
(ii) Show a typical block diagram of the array, showing the row and column buffer blocks, refresh circuitry amongst others.
