SK Hynix to Show Off its GDDR7, 48GB 16-layer HBM3E Stacks
 

Samsung isn't the only Korean memory giant showing off its latest tech at the upcoming IEEE Solid State Circuit Conference (SSCC) in February, 2024; it will be joined by SK Hynix, which will demo competing tech across both its volatile and non-volatile memory lines. To begin with, SK Hynix will be the second company to show off a GDDR7 memory chip, after Samsung. The SK Hynix chip is capable of 35.4 Gbps speeds, which is lower than the 37 Gbps Samsung is showing off, but at the same 16 Gbit density. This density allows the deployment of 16 GB of video memory across a 256-bit memory bus. Not all next-generation GPUs will max out 37 Gbps, some may run at lower memory speeds, and they have suitable options in the SK Hynix product stack. Much like Samsung, SK Hynix is implementing PAM3 I/O signaling, and a proprietary low-power architecture (though the company wouldn't elaborate on whether it's similar to the four low-speed clock states as the Samsung chips).
