Major memory manufacturers are actively working on the next generation of desktop and server memory — DDR6. According to South Korean outlet The Elec, SK hynix, Samsung, and Micron have begun designing DDR6 modules in their labs and are collaborating with substrate makers under JEDEC’s supervision to establish the new standard.
While a first draft of the DDR6 specification has been available since 2024, key details such as voltage ranges, signal usage, power requirements, and pinouts are still being finalized. The industry is now accelerating development to move the standard forward.
Expected Performance
- Starting speed: 8,800 MT/s
- Future target: Up to 17,600 MT/s (nearly double the top speed of current DDR5)
- New architecture: 4×24-bit sub-channel design (compared to DDR5’s 2×32-bit)
To handle the higher speeds and overcome physical limitations of traditional DIMMs, the industry is expected to rely heavily on CAMM2 technology. Server platforms are likely to adopt DDR6 first, followed by high-end notebooks once production scales up.
Timeline Update
Last year, the target was a 2027 launch. However, that timeline now appears to refer mainly to customer validation and testing. Commercial shipments are currently expected in 2028.
With DDR5 adoption reaching around 90% this year (up from 80% last year), DDR4 is increasingly being phased out. This shift should free up manufacturing capacity for the new DDR6 modules.
