Samsung becomes first to introduce 12-stack HBM3E amid high demand from AI

Samsung said on Tuesday that it has developed the industry’s first 12-stack HBM3E DRAM, making it a high bandwidth memory with the highest capacity to date. The South Korean tech giant said the HBM3E 12H DRAM provides a maximum bandwidth of 1,280GB/s and a capacity of 36GB. The bandwidth and capacity are all up by 50% compared to 8-stack HBM3, Samsung said. HBMs are comprised of multiple DRAM modules stacked vertically, each called a stack or a layer. In the case of Samsung’s latest, each DRAM module has a capacity of 24 gigabits (Gb), equivalent to 3 gigabytes (GB), and there are twelve of them. Memory makers Samsung, SK Hynix, and Micron are competing to stack more while limiting the height of the stacks to make the chip as thin as possible with more capacity. All three are planning to increase their production output of HBM this year, with the downcycle of the memory chip market seemingly over, and to meet the high demand from the popularity of AI, which has increased demand for GPUs …
