A Fully Automated Method to Create Monte-Carlo MOSFET Model Libraries for Statistical Circuit Simulations

Wang J., Trombley H., Watts J., Randall M., Wachnik R., IBM Semiconductor Research and Development Center, US

As the MOSFET continues to shrink, device-to-device variations become increasingly important. Therefore, it is critical to develop accurate, Monte-Carlo (MC) models that capture various device variations to allow statistical circuit simulations. To model the global [...]

On the Variability of HfOx RRAM: From Numerical Simulation to Compact Modeling

Guan X., Yu S., Wong H.S.P., Stanford University, US

The trap-assisted conduction and filamentary switching mechanisms of the HfOx based resistive memory are studied. A numerical simulator is developed to reproduce the experimental I-V curves. Comparison with experiments shows that the cycle-to-cycle variation in [...]

Model Implementation for Accurate Variation Estimation of Analog Parameters in Advanced SOI Technologies

Suryagandh S., Subba N., Wason V., Chiney P., Wu Z-Y, Chen B.Q., Krishnan S., Rathor M., Icel A., Advanced Micro Devices, US

Analog design uses transistors with longer channel length for high performance. gm, Rout and intrinsic gain form the matrix to gauge this performance. It is critical to design these circuits for manufacturing variability. This work [...]
