Weebit Nano Demonstrates Its First Crossbar ReRAM Arrays

Weebit Nano Limited announced that together with its development partner CEA-Leti, it has demonstrated its first operational crossbar arrays, a key milestone on the company’s path to creating discrete, stand-alone, non-volatile memory (NVM) chips.
The 1T1R (one transistor one resistor) architecture used in embedded ReRAM arrays is not sufficient to support the large arrays of memory cells needed in discrete memory chips. For this reason, Weebit’s crossbar arrays were developed using a 1S1R (one selector one resistor) architecture that enables the high density needed for discrete chips. Such an architecture also allows Weebit’s arrays to be stacked in 3D layers so they can deliver even higher densities.
Weebit’s 1S1R crossbar ReRAM architecture has potential applications in storage class memory, persistent memory, and as a NOR flash replacement. It is also ideal for AI architectures such as in-memory computing and neuromorphic computing.
Commenting on the Company’s latest technology development milestone, CEO Coby Hanoch said: “Weebit Nano continues to make significant technical and commercial progress within the embedded sector – recently successfully scaling our ReRAM technology down to 28nm. Now, with the creation of our first kilobit crossbar arrays, we’re continuing our progress toward discrete memory solutions.
Developing such a crossbar array is a very innovative process that requires significant research. As part of this work, we recently filed several new patents together with CEA-Leti, designed to further protect Weebit’s ReRAM intellectual property, with a focus on 1S1R architectures and selector cell programming.”
