The world’s largest memory chipmaker said it developed 512GB DDR5 (Double Data Rate 5) memory modules based on a High-K Metal Gate (HKMG) fabrication process that’s 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 chips out to developers of data centre 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.”
