The design of Dynamic Random Access Memory (DRAM) pass transistors is provided via generating a first plurality of transistor leakage currents by simulating different dopant configurations in a transistor; generating a second plurality of transistor leakage currents by simulating, for each dopant configuration of the different dopant configurations, a single trap insertion in the transistor; fitting the first and second pluralities of transistor leakage currents with first and second leakage current distributions; combining the first and second leakage current distributions to produce a third leakage current distribution; generating a third plurality of statistically generated leakage currents for a specified trap density for the transistor based on the first leakage current distribution, on the second leakage current distribution and on a specified trap density; and modeling and evaluating a DRAM cell including the transistor based on the third plurality of statistically generated leakage currents.
