Samsung Talks DDR6-12800, GDDR7 Development, and HBM3 Volume Production

During Samsung's Tech Day 2021, the company presented some interesting insights about the future of system memory technologies and how it plans to execute its production. Starting with the latest DDR5 standard, the company intends to follow JEDEC documents and offer some overclocking modules that surpass the specification advised by JEDEC. While the DDR5 standard specifies memory modules with 6,400 MT/s, Samsung will develop modules capable of overclocking up to 8,400 MT/s. These are not yet confirmed as they are still in the development phase. However, we can expect to see them in the later life of DDR5 memory.

The company also talked about the DDR6 standard, which is supposedly twice as fast as DDR5. The new DDR6 standard is still in early development, and all we know so far is that the number of memory channels per module is seeing a twofold increase over DDR5 to four channels. The number of memory banks also increases to 64. In addition to DDR6 for desktop and server use cases, the company is also working on Low Power DDR6 (LPDDR6) for mobile applications. While the company's LPDDR5 memory goes into volume production using the 1a-nm process at the beginning of 2022, the LPDDR6 is still in early development. The base speed for DDR6 modules will allegedly arrive at 12,800 MT/s, while overclocking modules will join the party at up to 17,000 MT/s. Mobile-oriented LPDDR6 version is also supposed to come with up to 17,000 MT/s speeds.
