According to Korean media citing industry sources, although Samsung's initial HBM4 yield during mass production in February of this year briefly fell below 60%, its yield has recently approached 80%, which is about four months ahead of the original year-end target of 80%. Previously, Samsung Electronics stated during its quarterly earnings conference call that HBM4 sales in the second half of the year would easily exceed 60% of total HBM sales. In addition, reports indicate that Samsung Electronics has set an internal goal to raise its HBM market share to a level close to its overall DRAM market share (approximately 38%) by the end of the year.
