VIEWPOINT 2026: Sanjeev Aggarwal, CEO, Everspin TechnologiesWhy Memory Decisions Are Shifting
We are seeing this clearly with non-volatile memory. In edge systems, for example, the ability to remain powered down until computation is needed, then wake up instantly, changes the entire power equation. In industrial systems, power loss happens. When it does, the system has to come back up immediately with the data intact. If it can't do that, it becomes a problem very quickly, and that’s where standard memory solutions start to fall short. Aerospace applications bring a different constraint. For applications like low-Earth-orbit satellites or factory automation, memory has to work the first time, every time. There isn't time for long updates or recovery steps, and there’s no room for batteries just to keep data alive. If power drops, the system needs to come back up with the data intact and keep going. Interface standards are evolving as well. Designers are moving away from wide parallel interfaces, largely because of the area and power overhead they introduce. Serial interfaces make more sense. Octal SPI is already widely used. In some designs, teams look to DDR-style interfaces when bandwidth becomes the priority, but power remains the limiting factor and ultimately drives the decision. The industry is moving away from embedded solutions that require the use of coherent logic and memory. Advanced packaging that enables integration of chiplets of memory and logic from different CMOS nodes is a cost-effective solution.
