Development of next-generation memory technology is being driven by the growth of cloud and enterprise data center applications, artificial intelligence, autonomous cars, augmented reality, embedded vision, and High Performance Computing (HPC). Dual Data Rate (DDR) Synchronous Dynamic Random-Access Memory (SDRAM) technology is the de facto memory used in almost all applications, from data-center to mobile use cases. This is due to DDR’s high density and straightforward architecture (using a capacitor as a storage element), low latency, and low-power consumption. DDR4 is the most current iteration of DDR technology, with DDR5 at being rolled out in 2021. Let's mention of few key facts about each:
- DDR4 delivers higher performance, higher DIMM capacities, improved data integrity and lower power consumption.. LPDDR4 is the mobile equivalent of DDR4 memory. New features enhanced DDR4 memory’s signal integrity and improved the stability of data transmission/access.
- DDR5 once again extends the capabilities of DDR memory, doubling the peak memory speeds while greatly increasing memory sizes as well. Compared to its predecessor DDR4 SDRAM, DDR5 is planned to reduce power consumption, while doubling bandwidth. DDR5 doubles the bandwidth of DDR4, which tops out at 3.2 Gbps.
Poll Question: element14 is planning on some educational activities on DDR4 memory. What should be the emphasis: DDR4, DDR5, or a little of both?
