- The AMD patent reveals a new RAM design aimed at overtaking DDR5 data bandwidth
- The proposed HB-dimm approach uses pseudo channels and buffer chips to increase flow
- AMD’s past memory companies have struggled, raising questions about New Patent’s commercial path
AMD apparently developed a way to push memory performance beyond the current DDR5 limits, according to a newly published patent.
Spotted by Tech4gamers,, The deposit concerns, “an architecture of high bandwidth memory module” which could potentially double data flows without modifying the underlying DRAM chips.
The proposed design reaches up to 12.8 GBPS on the memory bus, compared to the 6.4 Gbit / s.
Not the first AMD memory rodeo
It does it thanks to the use of double-band double-band memory modules, or HB-DIMMS, which combine several dram chips with buffer fleas.
These buffers manage data transmission at twice normal speed, effective bandwidth with today’s technology rather than requiring an entirely new standard.
The use of pseudo channels and an intelligent signal routing to improve flow is also covered in the patent.
A recording circuit of the clock pilot decodes memory controls and uses a chip identifier bit to direct signals to independently addressable channels.
This will allow parallel access and flexible blocking methods to help maintain DDR5 compatibility.
Data transfer would use an uninterlined format to simplify signal integrity and reduce latency.
AMD maintains that the DDR5 deposit has struggled to respond to bandwidth requests for graphic processors and servers, which makes the architecture of the module required.
By allowing configurations to switch between pseudo-channel and Quad-Rank modes, it would be possible to adapt the design for high performance IT, AI workloads and game systems that require faster memory.
This development comes as competitors continue their own solutions. The NVIDIA SOCAMM 1 SOCAMM 1 project was abandoned after technical problems, the company now working on Socamm 2 as, separately, are Samsung, SK Hynix and Micron.
Although these efforts are focused on modular conceptions and extreme data flow rates for data centers, AMD’s proposal is positioned as an adaptable improvement for existing DDR5 systems.
It would not be the first time that AMD has entered the memory of the memory of course. In 2012, the company teamed up with Patriot Memory and Visiontek to sell brand DDR3 kits, although this company was not a huge success.
It remains to be seen whether the new patent will lead to a commercial product, but this is another example of the growing pressure on the industry to find ways to exceed the current DDR5 roadmap.
