Chip Talk > Unleashing New Opportunities: The Breakthrough of 40nm HV OTP IP in Display Technology
Published August 13, 2025
In a significant advancement for semiconductor technology, Chuangfeixin, a leading name in the realm of integrated circuit design, has completed the commercial rollout of its one-time programmable (OTP) memory IP developed for high voltage (HV) processes, specifically engineered using the 40nm node technology. This milestone was achieved through stringent validation processes at two prominent domestic foundries, solidifying Chuangfeixin’s position as a pivotal player in the semiconductor IP landscape.
The newly released 40HV OTP IP, designed for integration into OLED display driver applications, capitalizes on Chuangfeixin's matured anti-fuse OTP technology. This tech doesn’t require changes to existing manufacturing processes, aligning seamlessly with standard CMOS processes and ensuring significant yield improvements. Additionally, with enhanced redundancy architecture and error correction code (ECC) technology, it considerably boosts reliability and yield.
The IP is characterized by various features, such as: - Reliable Performance: The OTP IP can withstand environments of up to 125°C for up to a decade, showcasing its reliability for long-term applications. - High Capacity: With support for storage capacities of 64Kbytes and 16Kbytes, it addresses the complex data storage needs of modern display technologies. - Industry Validated: Having been mass-produced since 2015, it underscores its readiness for high-volume manufacturing, serving industry-leading clients in the display driver sector.
As OLED and AMOLED displays gain momentum across various applications, from smartphones to large TVs, the need for robust, reliable memory solutions increases. Chuangfeixin's 40HV OTP IP caters to these needs by ensuring high display uniformity and color accuracy through its brightness and color correction data storage capabilities. Furthermore, it enhances panel image quality by storing data for uniformity compensation, ensuring long-term data stability.
The flexible configuration options for driving parameters like current and voltage further allow it to meet the diverse driving requirements of AMOLED/PMOLED systems, paving the way for function customization and upgrades.
Security is paramount, especially as IoT devices proliferate. The OTP IP employs unique identifiers and encryption keys to offer hardware-level protection, mitigating risks associated with firmware tampering. This security reinforcement is vital in modern intelligent endpoints.
The integration of 40HV OTP IP into foundries exemplifies the expanding ecosystem for domestic high voltage process platforms. By reinforcing Chuangfeixin's technological edge in non-volatile memory, it lays a foundational role in bolstering China’s capabilities in producing indigenous display driver chips, IoT devices, and high-security endpoints.
In conclusion, Chuangfeixin's development represents not only a technological triumph but also a strategic enhancement of domestic capabilities in the semiconductor sector. As these technologies continue to mature and propagate, the broader industry is set to see new waves of innovation enabled by reliable, high-performance semiconductor IP solutions.
