Weebit Nano tapes-out first 22nm demo chip

HOD HASHARON, Israel – Jan. 3, 2023 – Weebit Nano Limited (ASX:WBT), 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 or RRAM) 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.
