The second, and related, change is coming through new memory technologies. SRAM and DRAM have been optimized for speed, density, and performance for a long time. But DRAM scaling has stalled, and SRAM suffers from variability at the newest nodes, making it difficult to maintain density. New memory types, based on different physics, could finish up being better, but this is possibly not the primary benefit.

For example, if ReRAM is adopted, memory cells inherently become analog, and this opens up a number of possibilities. “One of the foundational ideas of analog is you can actually compute in the memory cell itself,” says Tim Vehling, senior vice president for product and business development at Mythic. “You actually eliminate that whole memory movement issue, and therefore power comes down substantially. You have efficient computation and little data movement when analog comes into play. With analog compute-in-memory technology, it’s actually orders of magnitude more power efficient than the digital equivalent.”
