Samsung Electronics HBM4 Revenue Tops $1 Billion, Just Four Months After Becoming First to Mass Produce Samsung Electronics' sixth generation high bandwidth memory (HBM), HBM4, is reported to have become the first in the industry to surpass $1 billion (about 1.54 trillion won) in revenue. According to industry sources on the 23rd, Samsung Electronics posted these results as demand for HBM4 surged recently. Samsung achieved this roughly four months after it became the world's first to begin mass production shipments of HBM4 on February 12. If the cutoff point is set at the end of June, revenue is expected to exceed $1.2 billion (about 1.85 trillion won). As supply of Samsung's HBM4 has ramped up quickly right from launch, Samsung's share of the HBM market is also assessed to be expanding significantly.
