Weebit Resistive RAM (ReRAM) is a new type of Non-Volatile Memory (NVM) that is designed to be the successor to flash memory. The ReRAM IP can provide a high level of differentiation for System-on-Chip (SoC) designs, with performance, power, cost, security, environmental, and a range of additional advantages compared to flash and other NVMs.
The vendor’s first ReRAM IP product is available now in SkyWater Technology’s 130nm CMOS process (S130). The technology is fully qualified, available for integration in SkyWater’s users’ SoCs, and ready for production.
