The JESD79-5 DDR5 SDRAM specification signaled the transition to DDR5, with significant improvements in capacity, speed, voltage, and ECC functions. The new standard touts a host of crucial performance improvements and power savings over its predecessor. Early adoption should happen by Q4, but in the long term, most industries should feel the benefits of DDR5 in 5G, deep learning, AI, edge computing, smart medical, supercomputing, and mission-critical applications.
