Session 12 overview: DRAM: Memory subcommittee

Demand for high-performance and high-capacity DRAMs is increasing more dramatically than in the past, due to the emergence of new areas such as machine learning, VR and AR. In line with this trend, new innovations with capacities of 16Gb and data-rate speeds of 18Gb/s/pin are introduced this year. These changes are common to high-performance computing, gaming graphics, mobile, and server fields, including artificial intelligence. Two graphics DRAM papers of the next generation GDDR6 standard show a maximum data rate of 16 to 18Gb/s/pin with single-ended signaling, and 16Gb high-density DRAMs in a 10nm process node are introduced in LPDDR4X and DDR4. HBM2 is extended to an 8H stack for 64Gb density while keeping a BW of 341GB/s.
