For the first time, we comprehensively evaluate 6T SRAM stability and performance using monolayer and bilayer transition metal dichalcogenide (TMD) devices based on the ITRS 2028 (5.9 nm) node. Our study indicates that, with excellent device electrostatics and superior stability, the monolayer TMD is favored for low-power SRAM applications, while the bilayer TMD, with higher carrier mobility, is more suitable for relaxed channel length and high-performance SRAM applications.

This paper evaluates monolithic 3-D logic circuits and 6T SRAMs composed of InGaAs-n/Ge-p ultra-thin-body MOSFETs while considering interlayer coupling through TCAD mixed-mode model. This paper indicates that monolithic 3-D InGaAs/Ge logic circuits provide equal leakage and better delay performance compared with planar 2-D structure through optimized 3-D layout. The monolithic 3-D InGaAs/Ge 6T SRAMs can simultaneously improve the cell stability and performance through optimized 3-D layout. We suggest two 3-D SRAM layout designs for high performance and low power applications, respectively. Moreover, with optimized 3-D layout designs, InGaAs/Ge logic circuits exhibit larger delay improvement, and the 6T SRAMs exhibit larger read access time and time-to-write improvement compared with Si counterparts.
