High-Reliability Non-Volatile Memory Solutions for Industrial Programmable Logic Controllers
FRAM (Ferroelectric Random Access Memory) is extensively integrated into industrial Programmable Logic Controllers (PLCs) across manufacturing, automation, energy and process control sectors. With its fast write speeds, unlimited read/write cycle life and inherent non-volatility, FRAM addresses the critical memory challenges faced by PLCs operating in harsh industrial conditions.
Unlike traditional flash memory or EEPROM used in PLCs, Smart Memories FRAM requires no delay for data writing (instant non-volatile storage), consumes minimal power during write operations, and eliminates the risk of data corruption during sudden power outages. This makes it the optimal memory solution for PLCs that demand continuous, high-frequency data logging, program retention and configuration storage in extreme temperature, vibration and electromagnetic interference (EMI) environments.
Stores real-time industrial process data including temperature, pressure, flow rate and motor speed at high sampling rates. FRAM's unlimited write cycles eliminate memory wear-out, while instant write capability ensures no data loss during rapid process changes or power interruptions.
Retains critical PLC program logic, I/O configuration parameters and calibration data without battery backup. FRAM's non-volatile nature ensures program integrity even after long-term power loss, reducing maintenance costs and downtime in industrial automation systems.
Captures and stores PLC system fault codes, alarm events and operational logs for root cause analysis. Fast write speed ensures millisecond-level event timestamp accuracy, while high reliability guarantees data integrity in harsh industrial environments (-40°C to 85°C).
Supports data synchronization between primary and backup PLCs in redundant systems. Low power consumption and fast read/write performance enable seamless failover without data latency, ensuring uninterrupted operation in mission-critical applications like power plants and manufacturing lines.
