Weebit Nano to collaborate with Israel Institute of Technology on real processing-in-memory project

The research project will look to speed up processing, memory transfer rate and memory bandwidth, as well as decrease potency latency, while also using much less power.

Weebit Nano Ltd (ASX:WBT) is to collaborate in research with the Israel Institute of Technology (Technion) to examine the possible use of ReRAM memories in a novel computing architecture.

The company and the team at the Technion, led by Professor Shahar Kvatinsky, will perform characterisation and implementation of logic operations using Weebit’s SiOx ReRAM test chips.

This is to demonstrate basic logic operations on a ReRAM array using the Technion’s MAGIC (Memristor Aided Logic) technique implementing ‘real processing-in-memory’ (real PIM).

READ: Weebit Nano achieves excellent test results for its memory technology

Weebit chief executive officer Coby Hanoch said the company was constantly looking for opportunities to utilise its ReRAM in the most advanced and innovative fields.

Hanoch said: “We believe that ReRAM, in addition to being the next generation memory element, will also be part of the computing revolution enabling novel architectures mixing logic and memory to allow significant power-efficient processing-in-memory computing.

“We believe that by collaborating on this with the Technion, one of the leading research institutes in this domain, we can better prepare for yet another use for our unique SiOx ReRAM technology.”

Potential to revolutionise current computing architectures

Although ReRAM technology is targeted for next generation memory devices, there is huge potential for ReRAM to be used as logic circuits to revolutionise current computing architectures.

Traditional computing architectures, or ‘von Neumann’ architectures, have a clear distinction between processing and memory – the memory component and central processing unit (CPU) are separate devices, with memory serving only as ‘dumb’ storage from which the CPU reads and writes.

These ‘read’ and ‘write' transactions require substantial amounts of time and energy, increasing the power consumption of the chip and being relatively slow.

Real PIM enables up to 1,000-times less power use

With real PIM, ReRAM elements are used as ‘logic gates’, allowing the computer to perform logical operations inside the memory on the same devices that store data.

In other words, the computer can perform computation inside the ReRAM arrays rather than in the CPU.

This is much faster and uses up to 1,000-times less power by avoiding the need to export and import data between the memory chip and CPU.

Collaborative approach

The Technion’s professor Kvatinsky said the institute had been investigating real PIM for several years.

Kvatinsky said: “Our MAGIC technique utilises the unique characteristics of emerging memories such as ReRAM where the same cells can be used for both memory and logic.

“We are very proud to cooperate with Weebit, a leader in the ReRAM domain, on this research and to use their test chips as the basis for this research.”
