TrendForce reports that significant capital investments have occurred in the memory sector due to the high ASP and profitability of HBM. Senior Vice President Avril Wu notes that by the end of 2024, the DRAM industry is expected to allocate approximately 250K/m (14%) of total capacity to producing HBM TSV, with an estimated annual supply bit growth of around 260%. Additionally, HBM's revenue share within the DRAM industry—around 8.4% in 2023—is projected to increase to 20.1% by the end of 2024.

HBM supply tightens with order volumes rising continuously into 2024
Wu explains that in terms of production differences between HBM and DDR5, the die size of HBM is generally 35-45% larger than DDR5 of the same process and capacity (for example, 24Gb compared to 24Gb). The yield rate (including TSV packaging) for HBM is approximately 20-30% lower than that of DDR5, and the production cycle (including TSV) is 1.5 to 2 months longer than DDR5.
