The ultra-low-power memory specialist sureCore is recruiting engineers having 10 years or more experience in memory design. Its embedded SRAM IP targets system-on-chip (SoC) designs that serve wearable and Internet of Things (IoT) applications and are sensitive to power consumption, heat dissipation, and battery life.
The Sheffield, England-based company claims that its specially designed SRAM IP can cut memory power requirements by up to 50%, and that’s crucial in ever-more intelligent wearable designs. On the other hand, using off-the-shelf memory can consume up to 50% of the available power budget of a wearable device.

Embedded memory has become increasingly prevalent in modern SoC designs due to support for multiple processors running numerous software applications. However, SRAM has traditionally been power-hungry, making it unattractive for developers of wearable electronics and IoT applications. What sureCore has done is dramatically cut both dynamic and static power through its suite of advanced circuit design techniques.
Take the silicon-proven SRAM EverOn technology, for instance. It extends operation to near-threshold voltages, the practical limit being the bit cell retention voltage. For even lower voltage operation, the MiniMiser Register File technology directly tracks the minimum operating voltage delivered by the logic. These memory solutions cut operational power when only low levels of computing are required.

The company offers a custom memory design service as well as ultra-low-power IoT reference platforms to demonstrate its memory-oriented technologies. At a time when artificial intelligence (AI) smarts mandate more memory on a chip, it’s interesting to watch the companies like sureCore that are challenging the fundamental limitations of conventional SRAM architecture for more efficient memory solutions.
