Question

In 2020, an access time of 5 nsec would be typical for which element of the memory hierarchy in a desktop processor system? You must elaborate your response using the memory hierarchy terminology established within the lecture module content. For full credit, your response must consist of at least 5 complete sentences, but not have more than 10 sentences.

Answer 1

• In 2020, access time of 5 nano seconds will be typical for DRAM ( DYNAMIC RAMS).
• At present, DRAM has a least access time of 50 nano seconds only.
• Whereas SRAM (CACHE) will have a least access time of less than 10 nano seconds.
• So according to the memory hierarchy, SRAM (CACHE) is at the top of memory hierarchy with fast access rates compared to DRAMS which are at next level in the memory hierarchy.
• Drams have a typical acess rate of 5 nano seconds in 2020.
• Srams can have less than 10 ns of access time.
