Modern computers employ a small amount of very fast memory, called cache, between the CPU and

RAM to speedup process execution. One of the reasons caches are faster is that they are built using

SRAM technology, which is faster than the DRAM technology used for RAMs (main memory). Would it

be a good idea if we retain the hierarchy shown on the slide, but start building our RAMs using the faster

SRAM technology? If yes, explain why. If no, state two drawbacks of doing so.
