What RAMXEED does

RAMXEED LIMITED is a specialized Japanese LSI (large-scale integration) manufacturer headquartered in Yokohama, Japan, that designs, produces, and supplies non-volatile memory semiconductors based on FeRAM (Ferroelectric RAM) and ReRAM (Resistive RAM) technologies. The company operates as Japan's only FeRAM manufacturer with continuous mass production since 1999, having accumulated 4.6 billion FeRAM units sold over 25+ years. RAMXEED was renamed from Fujitsu Semiconductor Memory Solution Limited effective January 1, 2025, formalizing its transition to an independent private limited company after operating within the Fujitsu group. The company's specialization spans both memory materials (PZT and HfO2-based ferroelectrics) and full LSI/ASIC design expertise, positioning it as a niche mass-producer with over two decades of accumulated process, circuit, and product know-how.

The product portfolio comprises standalone memory ICs — FeRAM with I2C, SPI, Dual SPI, and parallel interfaces from 4Kbit to 8Mbit, and ReRAM for ultra-low-power read applications — alongside FeRAM-embedded ASIC/ASSP solutions that integrate memory with analog, RF, wireless communication, and wireless power circuits. Notable product lines include UHF and HF band RFID chips, rotary encoder memory (MB85RDP16LX), cryptograph-less authentication ICs, battery-less electronic paper tags (with 8KB FeRAM and IP54 rating), and a FeRAM-embedded ASSP chipset (MB97R7100 RF chip + MS97R5430 16-bit AD converter measuring only 1.04 mm²) developed for SEED's smart contact lens platform. Beyond current products, the company is investing in next-generation memory architectures including SOT-MRAM (Spin-Orbit Torque MRAM) and Processing-in-Memory (PIM), the latter positioned for AI inference and memory-centric computing. ReRAM products are manufactured on consignment by foundry partner Nuvoton Technology Japan Corporation. The company maintains an active R&D footprint demonstrated by publication of Chapter 6 on HfO2-based ferroelectric materials with Wiley-VCH, co-development of ISO/IEC 18000-65 standard, and selection for Japan MIC's FY2025 R&D program for radio resource expansion.

Revenue is generated predominantly through hardware sales across three streams: standalone memory ICs (FeRAM, ReRAM), ASIC/ASSP products (RFID, authentication, rotary encoders, smart contact lens chipset), and application-level products (ePaper tags). The go-to-market is sales-led, combining direct enterprise engagement for custom ASIC development and large-volume accounts with a global distribution network spanning DigiKey, Mouser, Chip One Stop, KAGA FEI Europe, and regional resellers across the Americas, Asia/Oceania, EMEA, and Greater China. Customer segmentation covers industrial/factory automation, automotive electronics (infotainment, EDR, BMS), medical/healthcare (CT scanners, bedside monitors, smart insulin pens, smart contact lenses), IoT/wearables (hearing aids, ePaper tags), and office/consumer electronics. Named enterprise customers include Canon Inc. (awarded 'Excellent Procurement Partner' status for April 2025 – March 2027), DELTA ELECTRONICS, SEED, YAMASA NEXT, POSITAL, and UBITO. Pricing is not publicly disclosed and is quote-based, with multi-year contracts available for enterprise customers.
