Next-generation memory developer Weebit Nano (ASX:WBT) is working with its development partner CEA-Leti to scale its embedded ReRAM technology down to 22nm – one of the industry’s most common process nodes. The two companies are designing a full IP memory module that integrates a multi-megabit ReRAM block targeting an advanced 22nm Fully Depleted Silicon On Insulator (FDSOI) process.
Weebit’s first silicon wafers that integrate its embedded ReRAM module at 130nm have shown positive early test results, and the company has successfully demonstrated production level parameters at 28nm. Weebit is leveraging its strong balance sheet to accelerate its development plans to scale its technology to process nodes where existing embedded Flash technology is no longer viable.
Coby Hanoch, CEO of Weebit Nano, said: “We are excited to be developing our next memory module on a 22nm FD-SOI process. We continue to progress Weebit’s memory technology to smaller geometries that serve applications such as IoT, 5G and AI, which are driving the need for a new type of non-volatile memory in process nodes where embedded flash is no longer a realistic option. We have embarked on this new 22nm program to enable future customers to use our ReRAM technology to create exciting new products in advanced geometries.”
Olivier Faynot, Head of Silicon Component Division, CEA-Leti, said: “FD-SOI technology provides exceptional performance at very low voltages with low leakage and is broadly adopted by the industry. Combining ReRAM technology with FD-SOI holds great promise for low-power embedded devices, which need a new type of non-volatile memory and will benefit from its efficiency and robustness.”
