Micron talks 20Gbps GDDR6 memory

With a slight voltage bump

It appears that Micron will easily extend from its JEDEC 14Gbps transfer speed as, according to Micron, it can hit as high as 20Gbps with a slight voltage bump.

According to Micron's research paper, conveniently titled "16Gb/s and Beyond with SingleEnded I/O in High-Performance Graphics Memory", GDDR6 memory can easily scale as to speeds of 16.5Gbps and with "small, but helpful, boost in I/O voltage", it can go as high 20Gbps, at least on paper.

According to the paper, the 16.5Gbps result demonstrates full DRAM functionality that could be capped by timing limitations in the memory array itself and the 20Gbps speeds were achieved by placing it into a special mode of operation which uses only the I/O while bypasses the memory array.

While we won't see 20Gbps GDDR6 memory anytime soon, 14Gbps, 16Gbps, and the 18Gbps GDDR6 chips, recently announced by Samsung, will certainly provide a significant performance improvement for the next-generation graphics cards.

Hopefully, we will hear more about those next-generation consumer/gaming graphics cards soon but according to recent details, this won't be happening anytime soon.
