DDR4 Boom Boosts Memory Module Makers

As DDR4 prices surge sharply, not only are major upstream chip manufacturers like Nanya Technology and Winbond seeing strong momentum, but downstream memory module companies are also benefiting from favorable inventory positions. Companies such as ADATA, Apacer, and Innodisk have reported significant growth in June, driven by increased demand and advantageous procurement strategies.

ADATA Technology reported consolidated revenue of NT$4.698 billion in June, marking a 12.69% month-over-month increase and a 59.05% year-over-year growth — the highest single-month performance in over 15 years. Second-quarter revenue reached NT$12.784 billion, up 29.03% sequentially and 27.22% year-over-year, setting a new 15.5-year quarterly record. For the first half of 2025, ADATA's revenue totaled NT$22.684 billion, reflecting an 8.48% annual increase.

Chairman Simon Chen noted that rising customer inventory demand is driving strong order momentum, with the company committed to fully supporting key client requirements. Based on current visibility and the continued rise in memory prices, Chen expects second-quarter gross margins to outperform the first quarter, with growth expected to extend into Q3 and potentially set new operational highs.

Innodisk also saw a strong performance in June, with monthly revenue surpassing the NT$1 billion mark for the first time, reaching NT$1.03 billion — a 37.52% year-over-year increase. First-half revenue hit NT$5.647 billion, growing 29.34% compared to the same period last year. The company attributes its success to consistent progress in industrial control projects and early gains from its edge AI deployment strategy.

Looking ahead to the second half, Innodisk has proactively prepared inventory to meet projected demand amid ongoing global economic and geopolitical uncertainty. The company anticipates continued growth driven by stable project execution, ample stock, and accelerating edge AI adoption.

Apacer posted first-half revenue of NT$4.761 billion, up 24.31% year-over-year. The surge was fueled by a wave of urgent market orders following announcements by major manufacturers to halt DDR4 production, tightening supply. Additionally, increased demand for inventory replenishment in anticipation of tariff changes in the latter half of the year helped drive shipping momentum.
