The common issues of traditional poly-fuse include large device size, high power consumption, and limited storage space, which restrict the development of camera modules. eMemory’s OTP silicon IP features high read speed and low operating power, suitable for CMOS Image Sensors (CIS) and Image Signal Processors (ISP) applications.

It is ideal for poly-fuse replacement as it can be applied to functions such as identification, initial setup, lens shading correction, gamma correction, defective pixel correction, AF parameter setup, and key encryption. Embedded OTP silicon IP can prevent physical detection of the stored information and protect data and programs from being hacked, thereby improving the security of web-based cameras and monitors.

The external EEPROM traditionally used by camera modules has disadvantages including large footprint and additional power consumption as a result of the data transfer interface. eMemory’s MTP silicon IP is the perfect choice to resolve these issues as it features 10,000-100,000 endurances, high-temperature data retention ability, built-in charge pump, and low-operating power to enhance battery life.

eMemory’s MTP silicon IP can be applied to AF and OIS Controllers for functions such as identity authentication and Voice Coil Motor (VCM) Driver setting. By replacing external EEPROM with embedded silicon IP, customers can further reduce production cost to boost market competitiveness.

eMemory’s Logic NVM solutions targeting camera module applications have been extensively deployed in many process generations. The development of NeoFuse OTP silicon IP has been completed and it has entered production in 0.11um to 55nm CIS processes. It is also available in 55nm to 28nm low power processes for advanced ISP applications.

NeoBit OTP silicon IP is ready in 0.18um to 0.13um logic and BCD processes for PMIC applications, while NeoEE MTP silicon IP is available in 0.18um to 0.13um logic processes, providing highly reliable solutions for AF and OIS Controllers. The wide range of availabilities can facilitate customer deployments and speed up time-to-market, making eMemory’s solutions the best choice in aiding camera module vendors to grasp vast market opportunities.
