Product overview

Infineon's F-RAM (ferroelectric RAM) is a next-generation memory that combines the high-speed Access performance of STATIC RAMS with the non-volatility of FLASH MEMORIES. It boasts outstanding endurance, with over 10 trillion write cycles, and data retention for over 10 years. Furthermore, its low-power operation makes it ideal for applications requiring power efficiency and reliability, such as IoT devices, automotive systems, and industrial equipment. Conventional ELECTRICALLY ERASABLE PROMS and FLASH MEMORIES are limited in their write cycles and write speeds, making them difficult to store real-time data or frequently update logs. F-RAM overcomes these limitations, enabling instant data writes and high reliability. F-RAM is particularly ideal for systems requiring data protection during POWER SUPPLIES outages and frequent data updates.

Use cases and implementation examples

Use Case 1: Automotive ECU log management

[Use case overview]
Automotive ECUs need to record data related to engine control and safety functions in real time.
Conventional ELECTRICALLY ERASABLE PROMS have issues with rewrite lifespan and speed, and there are risks with frequent log updates and data retention during POWER SUPPLIES outages.
F-RAM has write speeds on par with STATIC RAMS, an endurance of over 10 trillion cycles, and the ability to instantly retain data even when POWER SUPPLIES is interrupted, significantly improving the reliability and safety of automotive systems.

[Major features]
High-speed write: Data is saved in milliseconds, supporting real-time control
High durability: Long life with over 10 trillion rewrites
Wide temperature range:-40℃ to +125℃, ideal for automotive environments

[Introduction Effects]
Improved reliability: Data is retained even when POWER SUPPLIES is cut off, reducing the risk of system failure
Cost reduction: No need to replace ELECTRICALLY ERASABLE PROMS, reducing maintenance costs
Enhanced safety: Ensure vehicle safety by reliably saving important logs

Use case 2: Smart meter data storage

[Use case overview]
Smart meters must record power usage at short intervals and retain data even during power outages or communication failures. Conventional memory suffers from issues such as shortened lifespan and data loss due to frequent writing. F-RAM consumes low power and writes data instantly, achieving data retention for over 10 years. This extends battery life, prevents data loss, and enables accurate billing and demand forecasting.

[Major features]
Low power consumption: Ideal for battery-powered devices
Instant write: Data is saved instantly even during a power outage
Long-term retention: Reliability is ensured with data retention of over 10 years

[Introduction Effects]
Reduced operating costs: Reduced frequency of battery replacement
Improved data reliability: Prevents data loss during power outages
Improved customer satisfaction: Accurate billing and stable service provision

Use Case 3: Industrial PLC Settings Retention

[Use case overview]
Industrial PLCs require frequent setting changes and log recording for factory automation and control. ELECTRICALLY ERASABLE PROMS 's write limitations and slow speed create bottlenecks, causing downtime and increased maintenance costs. F-RAM has a write endurance of over 10 trillion times, high-speed write performance, and retains settings even when POWER SUPPLIES is turned off. This increases equipment utilization rates and contributes to preventive maintenance and improved productivity.

[Major features]
High durability: Supports frequent setting changes
High-speed writing: Supports real-time control
Non-volatile: Settings are retained even when POWER SUPPLIES is turned off

[Introduction Effects]
Increased availability: Minimize downtime
Reduced maintenance burden: Reduced replacement and repair costs
Productivity improvement: Maximize line efficiency with stable operation
