- AMD -Patent reveals new RAM -Design aiming to double DDR5 -Databand width
- Suggested HB-DIMM approach uses pseudo channels and buffer chips to increase the flow
- AMD’s former memory companies fought and raised questions about New Patents’ commercial path
AMD has apparently developed a way of pushing memory performance beyond the current DDR5 limits, according to a recently published patent.
Stained off Tech4GamersAt Filing of filing, “a high-band width memory module architecture” that can potentially double data speeds without changing the underlying dram chips.
The proposed design achieves up to 12.8 Gbps on the memory bus compared to the DDR5’s original 6.4 Gbps.
Not AMD’s first memory rodeo
It does so using high-band width double memory modules or HB DIMM that combines multiple drama chips with buffer chips.
These buffers handle data transmission at double the normal speed, which effectively scales bandwidth with today’s technology rather than requiring a whole new standard.
The use of pseudo channels and intelligent signal routing to improve the flow is also covered by the patent.
A registry -river circuit decodes memory commands and uses a chip identifier bit to direct signals to independently addressable channels.
This allows for parallel access and flexible watch mode to help maintain DDR5 compatibility.
Data transfer will use a non-interleaved format to simplify signal integrity and reduce latency.
AMD argues in the filing of the DDR5 has struggled to follow the bandwidth requirements from graphics processors and servers, making an upgrade in the module architecture necessary.
When allowing configurations to switch between pseudo-channel and quad-rank modes, it would be possible to tailor the design for high performance calculation, AI workload and game systems that require faster memory.
This development comes when competitors pursue their own solutions. Nvidia’s former Socamm 1 project was abandoned after technical problems, where the company is now working on Socamm 2 as separately, is Samsung, SK Hynix and Micron.
While these efforts focus on modular design and extreme data rates for data centers, AMD’s suggestions are placed as an adaptable improvement for existing DDR5 systems.
This would not be the first time AMD of course has entered the memory arena. Back in 2012, the company collaborated with Patriot Memory and Visiontek to sell branded DDR3 sets, though this venture was not a huge success.
Whether the new patent will result in a commercial product is resettled to see, but it is another example of the growing pressure on the industry to find ways to move beyond the DDR5’s current roadmap.
