SureCore’s Ultra‑Low‑Power SRAM Cuts Memory Power by 50% for Wearables and IoT SoCs

The embedded SRAM IP from SureCore is engineered for system‑on‑chip (SoC) designs that power wearable and IoT devices, where every milliwatt counts.

Headquartered in Sheffield, England, SureCore seeks senior memory‑design engineers with at least a decade of experience to advance its next‑generation SRAM solutions.

According to the company, its proprietary SRAM IP can reduce memory power consumption by up to 50%—a figure that is critical when off‑the‑shelf memory can consume as much as half of a wearable’s power budget.

Embedded memory has become a cornerstone of modern SoCs, enabling multiple processors to run a wide array of applications. Yet SRAM has historically been a power drain, making it unattractive for wearables and IoT devices that demand ultra‑low power and high reliability.

SureCore tackles this challenge by slashing both dynamic and static power with a suite of advanced circuit techniques. Its silicon‑proven EverOn technology, for example, pushes operation close to threshold voltage—limited only by the bit‑cell retention voltage. For even lower voltages, the MiniMiser Register File dynamically tracks the minimum logic supply, ensuring optimal power use when compute demand is low.

Beyond IP, SureCore offers a custom memory‑design service and a portfolio of ultra‑low‑power IoT reference platforms that showcase its memory technologies in real‑world contexts.

As artificial intelligence continues to demand larger on‑chip memories, companies that push the limits of conventional SRAM—such as SureCore—are poised to deliver the next wave of efficient, high‑performance solutions.
