Samsung Electronics Co. announced plans for its next-generation memory chips that will double the speed of existing technology and offer the biggest capacity yet, kicking off a transition that will accelerate the growth of data centers and supercomputing.

The worlds largest memory chipmaker said it developed 512GB DDR5 (Double Data Rate 5) memory modules based on a High-K Metal Gate (HKMG) fabrication process thats traditionally been used in logic chips. DDR5 memory will be twice as fast as the current DDR4, while reducing leakage and using about 13% less power.
Samsung expects the transition to DDR5 to begin in the second half of this year. The chip industry has been anticipating the adoption of the new memory standard and support for it will arrive with Intel Corp.s upcoming Xeon Scalable processors, codenamed Sapphire Rapids. In addition to partnering with the two major CPU suppliers, Intel and Advanced Micro Devices Inc., Samsung has sent samples of its new memory out to developers of data center platforms, the company told Bloomberg News.

Analysts estimate DDR5 chips will be about 20% larger than DDR4 parts, leading to increased pressure on semiconductor supply chains. Samsung intends to begin shipments this year and gradually evolve both its fabrication processes — expanding the use of extreme ultraviolet lithography — and pricing, which will include a premium for the early period. The crossover between DDR4 and DDR5 will happen in the second half of 2023, the Suwon-based company said.
As the penetration rate of DDR5 gradually rises, the shortage of DRAM is expected to persist in 2022, said Avril Wu, Vice President at TrendForce Research. We also expect a 30-40% price hike to take place initially.
