Flash Hit Its Physical Limit. ReRAM Is the Replacement: WeeBit Nano's Ilan Sever

WeeBit Nano's ReRAM is displacing embedded flash below 22nm nodes, already automotive-qualified and licensed to two major IDMs.

• Flash hits a wall: Embedded flash stores charge on a floating gate, but below 28-22nm the charge shrinks to near single electrons, making the technology physically unscalable.
• ReRAM's cost edge: WeeBit Nano's OxRAM adds just 1-2 masks in the back-end-of-line versus ~8-10 masks (25-30% of total mask count) for embedded flash.
