发明名称 SRAM cell
摘要 Disclosed is an SRAM cell on an SOI, bulk or HOT wafer with two pass-gate n-FETs, two pull-up p-FETs and two pull-down n-FETs and the associated methods of making the SRAM cell. The pass-gate FETs and pull-down FETs are non-planar fully depleted finFETs or trigate FETs. The pull-down FETs comprise non-planar partially depleted three-gated FETs having a greater channel width and a greater gate length and, thus, a greater drive current relative to the pass-gate and pull-up FETs. Additionally, for optimal electron mobility and hole mobility, respectively, the channels of the n-FETs and p-FETs can comprise semiconductors with different crystalline orientations.
