Featured Applications
Industrial Automation
RAMXEED FeRAM enhances reliability, speed, and system availability in industrial automation equipment. Unlike EEPROM or Flash memory, FeRAM provides instant non-volatile storage without erase cycles, enabling real-time recording of operational parameters, event logs, and sensor data even during unexpected power interruptions. Its ultra-high endurance of up to 1014 write cycles supports continuous data updates over long product lifetimes. Typical applications include HMIs, PLCs, servo drives, rotary encoders, factory robotics, and smart factory systems, where fast recovery, reduced downtime, and reliable data retention are essential.
Smart Meters
RAMXEED FeRAM is widely used in smart meters and energy monitoring systems where accurate data logging and long-term reliability are critical. Thanks to its high write endurance and instant non-volatile storage, FeRAM can reliably record power consumption, outage events, and system status information even during power interruptions. It also stores critical pointer and event data that help maintain data integrity when used together with Flash memory. Typical applications include three-phase smart meters, energy management systems, and utility infrastructure requiring high-frequency logging and long service life.
Smart Building & Building Automation Systems
Modern building automation systems continuously monitor HVAC equipment, lighting, access control, and energy management platforms. RAMXEED FeRAM provides reliable storage for configuration parameters, sensor data, maintenance records, and event logs that are frequently updated during operation. Its instant write capability, low power consumption, and extremely high endurance help protect critical information even during unexpected power loss. FeRAM is an ideal solution for HVAC controllers, building energy management systems (BEMS), smart locks, security controllers, and other intelligent building applications requiring long-term reliability.
Elevator control systems
Elevator control systems require reliable storage of operational data to ensure passenger safety and minimize downtime. RAMXEED FeRAM enables high-speed recording of position data, movement parameters, braking information, and diagnostic logs while maintaining data integrity during power interruptions. Compared with conventional EEPROM solutions, FeRAM offers significantly higher endurance and instant non-volatile storage, making it suitable for continuous logging applications. Typical uses include PLC-based and microcontroller-based elevator control systems where long service life, fast recovery, and dependable operation are essential.
Automotive
RAMXEED FeRAM supports a wide range of automotive applications that require fast, reliable, and highly durable non-volatile memory. With up to 1013 write cycles and operation up to +125°C, FeRAM is ideal for battery management systems (BMS), event data recorders (EDR), digital tachographs, infotainment systems, and other vehicle electronics. Its instant write capability allows critical data to be stored immediately without erase delays, helping protect information during unexpected events or power loss. By combining high endurance, fast write performance, and automotive-grade reliability, FeRAM contributes to improved vehicle safety, efficiency, and system performance.
