Micron GDDR6 can hit up to 20Gbps with slightly higher voltage

Micron revealed its upcoming GDDR6 memory may eventually ship in much faster versions than previously expected. While the JEDEC standard calls for 14Gbps, Micron's testing revealed its GDDR6 memory tech can easily scale to 16.5Gbps. Furthermore, the memory maker said it can go as high as 20Gbps with a small boost in I/O voltage:

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.

It doesn't mean we're going to see 20Gbps GDDR6 memory chips anytime soon, but it does show GDDR6 has quite some runway.
