SK hynix to detail its HBM3 memory @ 896GB/sec, offered in up to 24GB

Update: SK hynix reached out to tech media to clear the air about its HBM3 detailing at ISSCC 2022, and that its HBM3 @ 896GB/sec is the same memory as the one the company unveiled back in October 2021 but with a different "standard of performance indication".

SK hynix will be detailing its latest under-development HBM3 memory spec at the ISSCC 2022 (IEEE International Solid-State Circuits Conference) with up to 24GB through 12-layer HBM3 DRAM. With capacities of up to 196Gb (24GB) the company is using TSV (through silicon via) auto-calibration and machine learning optimizations.

We know what to expect from the title of the session SK hynix is involved in is dubbed "A 192-Gb 12-High 896GB/s HBM3 DRAM with a TSV Auto-Calibration Scheme and Machine-Learning-Based Layout Optimization". FYI: "TSV" is through silicon via, but we don't know if this is prototype memory or something that will enter mass production and see SK hynix printing it onto devices en masse.

The original HBM3 spec from SK hynix was tapping out at 665GB/sec but then upgraded to 820GB/sec a few months later, and now we have another 10% more at up to 896GB/sec from the new SK hynix HBM3 memory.
