Cache memory is faster than conventional RAM because:OA. Cache memory is physically bigger than RAMOB. Cache memory requires constant refreshingOC. Cache memory uses dynamic RAMOD. Cache memory is constructed from a special type of memory chip called Flip-Flops

A computer system's main memory consists of 64K 64-bit words, and a two-way set-associative cache consists of 64 word-sized lines and has a total size of 512 words. Also, suppose that the cache is operated in an LRU manner and the time it takes to read a block from the main memory is 10 times the time it takes to read a block from the cache. When the cache is empty, the processor is 40h, 41h, 42h, ..., If you repeat accessing word 27Fh 10 times in order, how much faster is using the cache compared to not using the cache?
Akash M.
In a cache memory, cache line is 64 bytes. The main memory has latency of $32 \mathrm{~ns}$ and bandwidth of $1 \mathrm{~GB} / \mathrm{sec} .$ Then the time required to fetch the entire cache line from main memory is (A) $32 \mathrm{~ns}$ (B) $64 \mathrm{~ns}$ (C) $96 \mathrm{~ns}$ (D) $128 \mathrm{~ns}$
Computer Organization and Architecture
Cache and Main Memory, Secondary Storage
Cache. A 2-way set associative cache consists of 8 blocks. Byte-addressable main memory contains 4K blocks of 8 bytes each. Initially, the cache is empty. The least recently used (LRU) algorithm is used for the replacement policy. Show the main memory address format that allows us to map addresses from main memory to cache. Be sure to include the fields as well as their sizes.
