$1)$ Compare the cache write policies for mobile computers.

$2)$ Evaluate the cache replacement algorithms for desktop computers.

$3)$ Compare the RAM types, major properties, and cell structures in terms of performance levels.

$4)$ Explain the derivation of the check bit expressions and the interpretation of the syndrome word during the Hamming error$-$correction code to detect$/$correct a bit value, by using a $16-$bit data.

$5)$ Explain the ROM types and major properties for space applications.

$6)$ Accurately draw two possible chip organizations of a $4$ MB internal memory, whose cell$-$size is half$-$word configured.
