UMC’s embedded Non-Volatile Memory (eNVM) technology integrates reliable on-chip data storage directly into SoC and MCU designs, retaining critical information even when power is removed. It supports a wide range of applications, including firmware and code storage, device identification, security keys, trimming data, and configuration parameters. By eliminating the need for external memory, UMC’s eNVM solutions help improve system integration, reliability, power efficiency, and manufacturing flexibility.
Built on UMC’s proven logic and mixed-mode process platforms, these eNVM IP solutions enable robust integration into SoC and MCU designs across process nodes ranging from 0.35µm to 28nm. The IP is designed to work seamlessly with standard-cell and I/O libraries, reducing integration complexity and development effort. Reference design flows, together with related design and verification kits, further streamline implementation from initial design through tape-out.
UMC’s eNVM portfolio focuses on embedded MRAM, embedded RRAM, and eFlash technologies to address the evolving requirements of next-generation applications. Embedded MRAM and RRAM offer high endurance, fast access, low-power operation, and reliable data retention, making them well suited for applications requiring frequent data updates, high-performance embedded memory, and improved scalability. eFlash provides a proven and scalable solution for embedded code storage, firmware updates, and product customization.
These technologies support applications across automotive and general-purpose MCUs, industrial and IoT devices, edge-AI systems, smart cards, SIM cards, and other emerging products. Customers can select the most appropriate solution based on application requirements such as endurance, access speed, memory density, power consumption, and scalability. UMC also maintains supporting eNVM options, including EEPROM, MTP, OTP, and eFuse, for applications with specific legacy, moderate rewrite, or one-time-programming requirements.
