Intrinsic’s ReRAM looks to address the challenges faced by SoC developers seeking an embedded non-volatile storage solution for 22nm and smaller nodes now that flash is no longer a viable option. The technology has many advantages including flash-like density coupled with SRAM access times.
A wide range of applications will be able to benefit from such a solution including automotive, medical, wearables, AI, edge-AI and AIoT.
Embedded flash memory has been the trusted non-volatile workhorse and has allowed products to be delivered to customers with updated firmware provided via over-the-air downloads, ensuring that both bugfixes as well as new features could be provided quickly and easily.
However, it has become increasingly challenging to scale flash beyond 28nm. This is opening the gate to new memory technologies to fill the gap. The automotive market is said to be watching particularly closely as the drive towards increased autonomy demands higher processing power and much more embedded memory.
Flash will no longer scale with logic presenting a challenge to developers of advanced microcontrollers. As it is not practical to build the two technologies on the same chip, vendors have been pushed towards a two-chip solution, which is far from ideal from a power perspective.
Intrinsic aims to solve this problem by providing a non-volatile memory that can easily be built on the same advanced process nodes as the logic. This dramatically reduces both power consumption and removes potential data bandwidth bottlenecks and latency caused by using off-chip flash memory. Its technology can read data 10x to 100x faster and write it 1000x faster than existing solutions and is fabricated using standard processing techniques at the back-end-of-line, making it less complex and less expensive than other ReRAM solutions. This, coupled with its flash-like density and its high temperature resilience, make it especially attractive.
Commenting Paul Wells, CEO of sureCore, said, “Intrinsic has invented a breakthrough memory technology that will enable developers to exploit the density and performance of more advanced nodes and integrate its scalable non-volatile memory solution. We have years of expertise in optimising on-chip memory with our SureFIT Custom SRAM Design Service that has delivered bespoke optimised memory solutions tailored to meet applications needs. This has included both single instances as well as complete compilers.
“It has been a small step to extend this service to encompass Intrinsic’s ReRAM technology and exploit our design environment to deliver the associated verification and characterisation environments underpinning the value of a compiler. The use of a memory compiler is essential to maximise the commercial potential of a new memory such as ReRAM. We are delighted to be working with a fellow British memory company to help bring their novel memory technology to market.”
Mark Dickinson, Intrinsic’s CEO, added, “Underpinning the sureCore sureFIT service is a suite of powerful tools that will enable us to save many years of development effort had we had to create similar solutions from scratch. In addition, sureCore’s tools and techniques have been silicon proven and have been optimised over many years to deliver memories with the lowest possible power consumption and highest density. Both microcontrollers and evolving AI architectures using Intrinsic ReRAM will deliver higher performance at lower power envelopes than those realised using off-chip flash.”
