SureCore’s ultra-low memory technologies empower designers to create the reality of the metaverse

June 27, 2022 — Mark Zuckerburg believes so strongly that the future is the metaverse that he changed Facebook’s name to Meta. Suddenly, an old sci-fi word has become the hottest mainstream concept, with billions invested to create its virtual worlds with hardware like augmented reality smart glasses and full immersion artificial reality glasses.

“Both glasses and goggles need to be lightweight with a long battery life,” explains Paul Wells, founder and CEO of SureCore. “Because designers don’t want the latency of sending data back and forth from the cloud to the goggles, huge amounts of processing have to be done onboard, which therefore means large amounts of energy-guzzling memory for image and video. manipulation and localized high-performance compute. Since our innovative memory designs require up to 50% less power than standard, out-of-the-box memory, we believe our technologies will be the key to successful, portable, metaverse hardware.”

In particular, one of the main challenges is building an energy-efficient frame buffer to drive the displays. These large memory subsystems can be anywhere from 10 MByte to 100 MB in size and must support very high data bandwidths. They pose a huge power problem for developers. Not only is dynamic capability critical, as the screens may need to be updated regularly with video showing the most power-hungry demands. In addition, having such a large amount of active memory means extremely high leakage currents that can dominate the power profile at elevated temperatures. Out-of-the-box memory designs from both foundries and the major IP vendors are typically optimized for area and performance, with virtually no consideration for power consumption. This gives a flat, two-dimensional selection space that, rather appropriate for these three-dimensional augmented reality applications, is completely inadequate. sureCore, as part of its custom memory development service, sureFIT™, has provided memory subsystem solutions optimized for the Power, Performance, and Area (PPA) three-dimensional design space. In one AR customer engagement, SureCore was able to achieve more than 40% total energy savings compared to turnkey solutions.

While a custom solution offers the opportunity to develop the optimal solution for the target application, SureCore has a range of flow-optimized, off-the-shelf products that deliver market-leading flow profiles so urgently needed for these applications. Among which Everon™, PowerMiser™ and MiniMiser™. Further details can be found at on sureCore’s product page. Energy savings can be achieved at both nominal operating voltages and, more importantly, low to near threshold voltages, allowing application designers to tailor the power profile to performance requirements. SureCore memories provide single-rail, low-voltage operation, enabling direct logic connection and greatly simplifying system-level design considerations.

“As we’ve been saying for a while, power is the number one consideration for so many applications. With memory needs growing relentlessly, developers now have no choice but to look for alternative solutions. SureCore has the technology and can deliver the energy savings that are so desperately needed,” said Paul Wells, CEO.
