A second-order winner of the DRAM crunch just printed earnings. AP Memory (TWSE: 6531), the Hsinchu-based fabless designer of low-power specialty memory and silicon capacitors, reported Q1 2026 net profit of NT$660 million (about US$20.9M) per DigiTimes, up 91% year over year; Taipei Times reported the figure as NT$676 million versus NT$331 million a year earlier, more than doubled. Revenue came in at NT$2.1 billion against NT$975 million a year ago. Two products did the work, and neither is a commodity DRAM die.
The bigger contributor was IoTRAM, AP Memory's customized PSRAM and low-density LPDDR line aimed at wearables, IoT, smart displays, and edge AI compute. IoTRAM was 70% of Q1 revenue. Management said directly at the earnings call that the DRAM shortage forced customers off commodity supply and into IoTRAM substitutes, and that the migration pushed prices up. This is the practical face of what IDC, TrendForce, and Tom's Hardware have been describing at the macro level: Samsung (KRX: 005930), SK Hynix (KRX: 000660), and Micron (NASDAQ: MU) have reallocated wafers to HBM, leaving low-density and legacy LPDDR users without supply. Some of those users have working PSRAM alternatives, and AP Memory designs them.
The second story is S-SiCap, AP Memory's stack silicon capacitor product line for advanced packaging. Q1 S-SiCap revenue was NT$572 million versus NT$66 million a year ago. The Gen4 part hits 3.8 μF/mm² capacitance density, more than 50% above Gen3, and is targeted at embedded-in-substrate placement for AI and HPC accelerator packages. Taipei Times reported that AP Memory is to supply integrated passive devices for Intel's (NASDAQ: INTC) EMIB advanced packaging, while president Hung Chih-hsun said first shipments for embedded-in-substrate opportunities are scheduled this quarter and volume production begins in Q2 2026. EMIB competes with TSMC's (NYSE: TSM) CoWoS in advanced AI and HPC packaging, though the technologies are not identical. If that supply relationship holds, AP Memory has a structural seat at the AI packaging table independent of any commodity memory cycle.
Vertical Hybrid Memory, the company's 3D-stacked AI memory IP, was 2.6% of revenue with active discussions with data center operators ongoing. Worth watching but not yet material.
This is another clean datapoint for the same thesis: the memory ecosystem is bifurcating into AI/HPC-adjacent products growing fast and commodity DRAM/NAND in deepening allocation. Small specialty players with the right roadmap are getting pulled upward by the shortage rather than crushed by it.
