Weebit Nano and Silvaco develop new simulation capabilities to increase ReRAM adoption

20 February 2020 – Weebit Nano Ltd (ASX: WBT), a developer of next generation memory technology for the global semiconductor industry, and Silvaco, Inc., a leading global provider of software, IP, and services for designing electronic systems, today announced that they have successfully modeled the electrical behaviour of Weebit’s silicon oxide (SiOx) Resistive Random Access Memory (ReRAM) devices.

This new simulation model capability in Silvaco’s advanced Technology Computer-Aided Design (TCAD) solution, Victory Device™, accelerates the incorporation of Weebit’s ReRAM modules into advanced semiconductor designs used in the ‘discrete’ and ‘embedded’ memory chip markets and speeds Original Equipment Manufacturer (OEM) product development schedules by reducing technology testing stages.

Victory DeviceTM analyses the electrical, optical, chemical, and thermal behaviour of semiconductor devices. Its physics-based simulations dramatically speed up the design, fabrication, and commercial use of semiconductor device technology through the elimination of expensive and time-consuming experimental wafers during technology adoption by OEMs.

As part of a partnership program conducted throughout 2019, Weebit and Silvaco developed a TCAD solution that accurately models the electrical behaviour of Weebit’s ReRAM devices. This collaboration focused on the essential material processes in the resistive switching of SiOx ReRAM devices to gain an indepth understanding of their properties and was based on Weebit’s physical samples and data.

Commenting on Silvaco’s successful TCAD modelling of Weebit’s ReRAM technology, VP & GM of Silvaco’s TCAD Business Unit, Eric Guichard, said: “These results are excellent news for the semiconductor industry.

Having this new ReRAM TCAD model in our advanced device simulator will enable the semiconductor industry to more efficiently embed ReRAM technology in their designs, leading to shorter production development schedules. Through our collaboration with Weebit, a key player in the ReRAM market, we’re enabling our mutual customers to take advantage of the latest advancements in semiconductor technology.”

Coby Hanoch, Weebit CEO, said: “Silvaco provides state-of-the-art device models and TCAD tools that are widely used by semiconductor companies. Our successful joint development provides customers with early access to Weebit’s ReRAM technology on the most powerful simulation tools in the industry. The newly developed TCAD model will enable customers to fast-track the development and release of their nextgeneration products, while saving expensive and time-consuming runs in fabrication. Costly learning, development and testing cycles that take several months have now been eliminated. This is another key milestone step by Weebit to accelerate the adoption of its ReRAM technology by a larger number of global OEM customers in the discrete and embedded markets.
