SEOUL, Feb 12 (Reuters) - Samsung Electronics said on Thursday that it has started shipping the ‌latest high-bandwidth memory chips, HBM4, to unnamed customers, as ‌the chipmaker races to catch up with rivals in supplying to Nvidia.

The ​global rush to build AI data centers has fuelled demand for HBM, a type of dynamic random-access memory (DRAM) that helps process massive amounts of data generated by complex artificial intelligence applications.

Samsung, ‌the world’s top memory ⁠chipmaker, had been slow in responding to the advanced AI chip market, lagging behind rivals ⁠in supplying previous-generation HBM chips.

Samsung said its HBM4 delivers a consistent processing speed of 11.7 gigabits-per-second (Gbps), a 22% increase from its ​predecessor, HBM3E. ​Samsung said its latest chips ​can achieve the maximum ‌speed of 13Gbps, which helps mitigate growing data bottlenecks.

Samsung also said it plans to deliver samples for next-generation HBM4E chips in the second half of this year.

Samsung shares ended up 6.4% on Thursday.

RISING COMPETITION

SK Hynix said in January that it ‌aims to maintain its “overwhelming” market share ​in the next-generation HBM4 chips, which ​were in volume production, ​as it faces rising competition from Samsung ‌Electronics.

It also added that it aims ​to achieve ​the production yields of HBM4 similar to that of current-generation HBM3E chips.

Micron’s CFO also said it was in high-volume ​production of HBM4 ‌and has commenced customer shipments of HBM4.
