Weebit Nano tapes-out first 22nm demo chipWeebit ReRAM in 22nm FD-SOI process provides cost-effective, reliable embedded NVM for IoT, edge AI and other ultra-low power applications

3 January 2023

Weebit Nano Limited (ASX:WBT, Weebit or the Company), a leading developer of next-generation memory technologies for the global semiconductor industry, has taped-out (released to manufacturing) demonstration chips integrating its embedded Resistive Random-Access Memory (ReRAM) module in an advanced 22nm FD-SOI (fully depleted silicon on insulator) process technology.

This is the first tape-out of Weebit ReRAM in 22nm, one of the industry’s most common process nodes, and a geometry where embedded flash is not viable.

Weebit worked with its development partners CEA-Leti and CEA-List to successfully scale its ReRAM technology down to 22nm. The teams designed a full IP memory module that integrates a multi-megabit ReRAM block targeting the 22nm FD-SOI process which is designed to deliver outstanding performance for connected and ultra-low power applications such as IoT and edge AI.

As embedded flash is unable to scale below 28nm, new non-volatile memory (NVM) technology is needed for smaller process geometries. Weebit ReRAM in 22nm FD-SOI offers a low-power, cost-effective embedded NVM solution that can withstand harsh environmental conditions.


I watched a CNBC Jensen Huang interview from back in March and he said tape-outs can cost $100m, $50m, $30m depending on size but nothing under $10m. GlobalFoundries and STMicroelectronics are in the box seat.
