The double data rate synchronous dynamic random-access memory (DDR SDRAM) has evolved from a data rate of 0.4 Gbps to the next generation, DDR5, scaling to 6.4 Gbps. With DDR5, we can achieve higher bandwidth using less power per bit transferred, enabling us to do more computing on larger data sets. DDR5 satisfies high-performance memory demands driven by the data-centric next-generation intelligent products. With significant performance improvements and power gains over its predecessors, DDR5 also introduces several design considerations concerning higher speeds and lower voltages that raise a new set of signal integrity challenges to an integral part of the DDR interface, the package design.
