Bringing resistive RAM technology to volume production

14 September 2021

Weebit Nano Limited is collaborating with SkyWater Technology to bring its resistive RAM (ReRAM) technology to volume production.

Under the agreement, Weebit will transfer the ReRAM technology to SkyWater’s production fab and SkyWater will license the technology to offer the memory to its customers as embedded, non-volatile memory IP on its 130 nm CMOS process.

While cutting edge technology — such as microprocessors, 5G chipsets and more — require leading-edge manufacturing, Skywater said its 130 nm process is a sweet spot for a broad range of applications including analog, power management, automotive, internet of things and radiation-hardened designs.

ReRAM offers enhanced endurance and retention even at high temperature ranges, good toleration to radiation and electromagnetic fields and zero interference with front-end-of-line (FEOL) analog components. Weebit touts ReRAM has benefits over flash memory by allowing chip memory elements to be faster, less expensive, more reliable and more energy efficient.

The memory can be scaled to other technologies such as SkyWater’s 90 nm and carbon nanotube platforms while also being integrated with existing flows and processes, without the need for special equipment or large investments.
