Weebit Nano Restricted, a developer of reminiscence applied sciences for the worldwide semiconductor business, has taped-out (launched to manufacturing) demonstration chips integrating its embedded Resistive Random-Entry Reminiscence (ReRAM) module in a sophisticated 22nm FD-SOI (absolutely depleted silicon on insulator) course of know-how. That is the primary tape-out of Weebit ReRAM in 22nm, one of many frequent course of nodes, and a geometry the place embedded flash shouldn’t be viable.
Weebit labored with its improvement companions CEA-Leti and CEA-Listing to scale its ReRAM know-how right down to 22nm. The groups designed a full IP reminiscence module that integrates a multi-megabit ReRAM block focusing on the 22nm FD-SOI course of which is designed to ship excellent efficiency for related and ultra-low energy purposes resembling IoT and edge AI.
As embedded flash is unable to scale under 28nm, new non-volatile reminiscence (NVM) know-how is required for smaller course of geometries. Weebit ReRAM in 22nm FD-SOI presents a low-power, cost-effective embedded NVM answer which might stand up to harsh environmental situations.
Coby Hanoch, CEO of Weebit Nano, says “We’re delighted to have taped-out on schedule our first demo chip in 22nm. We’re persevering with to speed up Weebit’s path in the direction of extra superior geometries to fulfill a transparent market want in purposes resembling microcontrollers, IoT, 5G, edge AI and automotive. Embedded NVM is a key component of such designs, however since embedded flash is troublesome to scale under 28nm, many corporations need to rising applied sciences like ReRAM. There’s elevated curiosity from corporations wanting to make use of our ReRAM to create thrilling new merchandise in these areas.”
Olivier Faynot, head of Silicon Part Division, CEA-Leti, says, “FD-SOI know-how supplies excessive efficiency with low voltages and low leakage to allow units to function at larger frequencies with higher power effectivity. It additionally allows simpler integration of further options resembling connectivity and safety. With Weebit ReRAM obtainable on this course of, the business may have a extremely environment friendly and strong NVM choice for his or her future product improvements.”
Weebit’s embedded ReRAM module consists of an 8Mb ReRAM array, management logic, decoders, IOs (Enter/Output communication components) and error correcting code (ECC). It’s designed with patent-pending analog and digital circuitry operating good algorithms that considerably improve the reminiscence array’s technical parameters. Amongst different advantages, Weebit’s ReRAM know-how excels in harsh environmental situations together with excessive temperatures, radiation and electro-magnetic fields, making it very best for purposes resembling IoT, medical, automotive and industrial.
The demo chips comprise a full sub-system for embedded purposes, together with the Weebit ReRAM module, a RISC-V microcontroller (MCU), system interfaces, recollections and peripherals.
