Best answer 2 votes 2 votes TA1 = 0.95 * 30(HIT) + 0.05 * 330( CACHE ACCESS TIME + MEMORY ACCESS) TA2 = 0.95 * 30(HIT) + 0.05 * 300(MAIN MEMORY ACCESS as searching is done simultaneously) Therefore TA1 - TA2 = 1.5 ns Tushar Jain answered Jan 21, 2016 • selected Jan 21, 2016 by Arjun Tushar Jain comment Share Follow See all 4 Comments See all 4 4 Comments reply Sumit1311 commented Jan 21, 2016 reply Follow Share What does simulteneous access mean here then? I was assuming it as for first 30 secs also the memory access will be happening so I have taken it as 270. Is it not like that?
