Empirical Performance Models for 3TID Memories. Harvard Computer Science Group Technical Report TR-03-08.http://nrs.harvard.edu/urn-3:HUL.InstRepos:23574263Abstract—Process variation poses a significant threat to the performance and reliability of the 6T SRAM cell. In response, research has turned to new memory cell models, such as the 3T1D DRAM cell, as potential replacement designs. If designers are to seriously consider this new design, performance models are needed to better understand the behavior of this cell. We propose a decoupled approach for collecting Monte Carlo HSPICE data, reducing simulation times by simulating memory array components separately based on their contribution to the worst-case read critical path. We use this Monte Carlo data to train regression models, which accurately predict retention and access times of a 3T1D memory array with a median error of 7.39%.en-USResearch Paper or Report2015-11-16
