Weebit Nano announced a "significant breakthrough" in its nano-porous silicon-oxide (SiOx) RRAM memory devices development. Weebit has managed to scale down its device filament (the conductive path that either allows a current to flow or not) to a sub-5nm scale, without any deterioration of performance reliability.
Weebit, based in Israel, is commercializing technology originally developed at Rice University. The company is currently negotiating with "major semiconductor manufacturers" regarding joint venture development. The company expects to show a commercially viable product within 18 months.
