What AP Memory does

AP Memory (愛普科技股份有限公司, TWSE: 6531) is a Taiwan-based fabless semiconductor company founded in 2011 and headquartered in Zhubei City, Hsinchu County, that designs and markets customized memory IP and standard/custom memory products for IoT, mobile, AI, and HPC applications. The company operates through two principal business units — an IoT Business Unit shipping PSRAM/LPDDR products under the IoTRAM™ umbrella (including ApSRAM™, UHS PSRAM, Octal-SPI PSRAM, ULS PSRAM, LVpSRAM™, and Xccela™ PSRAM variants) at approximately 1 billion units per year, and an AI Business Unit that licenses and ships VHM™ (Very High-Bandwidth Memory) products based on proprietary Wafer-on-Wafer (WoW) 3D heterogeneous stacking technology for AI/HPC chip designers. A third product family, S-SiCap™ (Stack Silicon Capacitor) including discrete Gen3/Gen4 devices and an interposer form factor, addresses power-integrity and voltage-stability requirements in advanced packaging for AI servers, HPC, and high-end mobile SoCs.

The company's core technology centers on WoW 3D heterogeneous integration (enabling >4 TB/s bandwidth per GB and >10,000 I/Os within a reticle), proprietary ultra-low-power PSRAM architectures (ApSRAM delivering 4x bandwidth and 1/5 dynamic power versus conventional PSRAM), and DRAM-derived stacked capacitor technology adapted for silicon capacitor products (S-SiCap Gen4 reaching 3.8 µF/mm²). AP Memory holds 54 globally granted patents (21 granted in 2025), is a member of the UCIe industry consortium, and operates an ISO 9001:2015-certified quality management system. Strategic foundry relationships with TSMC and Powerchip Semiconductor Manufacturing Corp. (PSMC) underpin VHM wafer production, and a 2023 NTD 500 million equity investment in M3 Technology (6799 TW, 9.56% stake) extended the platform into HPC power management co-development.

AP Memory generates revenue through (1) volume memory product sales of IoTRAM™ PSRAM/LPDDR via direct sales and a global authorized distributor network (WPG, WT Microelectronics, Avnet, Mouser, Rutronik, Sanshin, and others), (2) a two-stage VHM™ model combining upfront IP licensing fees during customer chip design and wafer-level revenue at mass production, (3) UHS PSRAM IP controller licensing through partners such as Mobiveil and Arasan (e.g., the Sureboot™ 16-bit xSPI + PSRAM IP launched in May 2026), and (4) sales of S-SiCap™ silicon capacitors in discrete and interposer form factors. The customer base spans leading global semiconductor and platform companies — Renesas, Qualcomm, NXP, Infineon, Texas Instruments, STMicroelectronics, Sony Semiconductor Israel, Analog Devices, Ambiq, Alif Semiconductor, Synopsys, Cadence, GOWIN, GreenWaves, and Mindgrove — with R&D or sales subsidiaries in Taiwan, China (Hangzhou, est. 2018), and the United States (Beaverton, OR, est. 2012). Reported revenue grew 35.13% YoY to NTD 5.64 billion in 2025, with 2026 YTD (Jan–May) revenue up 104.71% YoY at NTD 3.65 billion.
