MIT 6.780J, 2008 Assignment 5 solutions Part 1 — Solutions removed due to copyright restrictions. Part 2 (a) If yield of individual amplifiers is 99.5%, the yield of a memory block with 256 amplifiers each of which must function is (0.995) 256 = 27.7%. This is the functional yield of chips containing one memory block each.

Unformatted text preview: (b) If there are four memory blocks per chip, the functional yield is (0.277) 4 = 0.6%. (c) If the memory block can be reconfigured to function with 25 or fewer defective amplifiers, the yield is now: 25 256 C k (0.995) 256 k (0.005) k k = We can use a Poisson approximation to this binomial distribution to ease evaluation, where = 0.005 256 = 1.28. Then the yield is given by 25 exp( ) k / k ! 1 k = 0...
