  2. What is the overall speedup if you make 85% of a program 15 times faster

Question 2

Consider a dynamic RAM that must be given a refresh cycle 64 times per ms. Each refresh operation requires 150 ns; a memory cycle requires 250 ns.

What percentage of the memory’s total operating time must be given to refreshes? Explain your answer and show your calculations.

Question 3

List and briefly define three newer nonvolatile solid-state memory technologies.

Question 4

What is the difference between DRAM and SRAM in terms of application? What is the difference between DRAM and SRAM in terms of characteristics such as speed, size, and cost? 

SOLUTION

DRAM (dynamic random access memory) and SRAM (static random access memory) are both types of computer memory, but they have different characteristics and are used in different types of applications.

DRAM is typically used as the main memory in a computer and is slower and less expensive than SRAM. It is also less dense, meaning that it requires more physical space to store the same amount of data as SRAM.

SRAM, on the other hand, is faster and more expensive than DRAM. It is typically used in specialized applications such as cache memory and register files, where high speed and low latency are more important than cost and density.
