| Abstract: | Different manufacturers' 64 K DRAM products have been studied to determine which circuit elements contribute towards the overall alpha-particle-induced soft error rate. This has shown that alpha hits on the bit lines are far and away the most important contributors to soft errors: cell, sense amplifier and peripheral circuit hits have insignificant effects. The results also indicate why bit lines are so sensitive. |
