Israel-based RRAM developer Weebit Nano has taped-out demonstration chips integrating its embedded ReRAM module to SkyWater Technology’s foundry. Weebit signed the agreement with SkyWater in September 2021 to transfer its technology to SkyWater's fab.
This is the first tape-out of Weebit's technology to a production fabrication. The technology will be available on SkyWater’s 130nm CMOS process, which is suitable for applications such as analog, power management, automotive, IoT and medical. Weebit says that its chips are designed with unique patent-pending analog and digital smart circuitry running smart algorithms, thereby significantly enhancing the memory array’s technical parameters
Weebit’s embedded ReRAM module includes a 256Kb ReRAM array, control logic, decoders, IOs (Input/Output communication elements) and error correcting code (ECC). SkyWater customers can now use the highly integrated demo chip as the final platform for testing and prototyping ahead of volume production.
In February Weebit announced that together with CEA-Leti iit has demonstrated its first operational crossbar arrays that combine its ReRAM technology with a selector. In November 2021, Weebit raised $25.7 million AUD from four Israeli institutional investment and pension funds.
