Memory Bandwidth

Post by penguin » Thu May 01, 2014 10:15 am


In an interview I was asked the question:

What is the maximum access bandwidth of 64bit, 100MHz, DDR SDRAM with latencies as 3-2-2.5-0.5. Also, calculate the bandwidth when a new random address is applied after 4 words read.

Any idea, how to solve this. I can calculate the best case bandwith, but don't know how to calculate with latencies.

Thanks in advance
