The random dopant fluctuation (RDF) of double gate (DG) MOSFET based 6-T SRAM is investigated with three-dimensional (3-D) statistical simulation. The doping profile is generated by matlab and the threshold voltage variation due to RDF is obtained by device simulation. Then the performance of DG MOSFET based 6-T SRAM is evaluated by feeding the results into a compact DG MOSFET model using HSPICE Monte Carlo simulation. The results show that pull down transistor dominates static noise margin (SNM) fluctuation and access transistor dominates write margin (WM) fluctuation.
