Samsung Aquabolt 8GB HBM2 2.4Gbps chips are go

The package, dubbed Aquabolt, delivers data transfer speeds of 2.4 gigabits-per-second (Gbps) per pin which Samsung says translates into a performance boost of almost 50 percent compared to its first-gen offering.

"With our production of the first 2.4 Gbps 8 GB HBM2, we are further strengthening our technology leadership and market competitiveness", said Jaesoo Han, executive vice president, Memory Sales & Marketing team at Samsung Electronics.

Samsung is among the companies developing and producing HBM2 and announced today it is starting mass production of its second generation HBM2, called Aquabolt.

Asserting Samsung's new found dominance and position in the fast-paced DRAM market with its first generation "Flarebolt" HBM2 already being used in many current and upcoming AMD graphics cards has resulted in Samsung overtaking Intel's top position in semiconductor revenue after over 24 years.


Behind the advancement in HBM2 generations is, of course, some interesting science. Four of these Aquabolt HBM2 memory controllers when stacked are able to churn out an eye opening data transmission speed of 1.2TBps.

To achieve these technical advances in the Samsung Aquabolt HBM2, Samsung had to revamp the TSV design, vertically connecting over 5000 TSVs per die and upgrading the thermal control, allowing for a massive bump in chip performance.

Samsung has started production of its second generation HBM2, dubbed Aquabolt. The new chip design includes an increased number of thermal bums for stronger thermal control, as well as an additional protective layer at the bottom that provides an increased physical strength for the entire package. While using so many TSVs can cause collateral clock skew, Samsung succeeded in minimizing the skew to a very modest level and significantly enhancing chip performance in the process. A release date hasn't been mentioned, Samsung unveiled its predece.
