Weebit Nano (WBT) has advanced its ReRAM selector to fit both embedded and discrete applications.
The company’s latest results revealed the ReRAM selector was suitable for both embedded and stand-alone use, which greatly increases the applications for Weebit’s technology.
Weebit and its development partner, CEA-Leti, demonstrated the potential of the Weebit ReRAM selector to achieve the high densities required for discrete chips using standard materials and tools.
In a memory array, a selector is used to ensure only specific cells are accessed, and all other cells are disconnected and not impacted. Embedded designs currently use a transistor as the selector device. However, transistors increase the cell area of a memory bit and cannot support the high densities required for discrete chips.
Weebit said its selector technology could fit embedded applications, enabling unprecedented non-volatile memory (NVM) densities for future system-on-chips (SoCs).
Results from internal testing also showed that the ratio between programming current and leakage current was at industry standard, signifying high on-state and low leakage current.
Weebit Nano CEO Coby Hanoch said the company had worked hard to create a ReRAM selector that could achieve high densities using fab-friendly materials and standard tools.
“Such a selector will make it easy and cost-effective for any foundry to integrate the technology into existing processes and offer it to their customers,” Mr Hanoch said.
“In addition, we’re breaking down a barrier by making it possible to use the same selector for both discrete and embedded applications.
“This is an important step forward on our roadmap for discrete products and is a compelling value proposition for companies developing advanced SoCs for applications like edge AI, which need a reliable, cost-effective replacement for embedded flash.”
While additional development is still required, Weebit said this new technology could be easily integrated into any CMOS (complementary metal-oxide-semiconductor) fab to potentially enable the high-capacity memory arrays needed while keeping size and power to a minimum.
Weebit Nano shares were up 2.45 per cent to $2.09 at 11:00 am AEDT.
