Applications
Smart meter
Smart meters provide utilities with accurate, real-time monitoring of energy. The data from smart meters is often transmitted over a variety of wireless networks. Using this real-time data, utilities can monitor usage and detect anomalies, leading to efficiencies and cost savings.
Smart meters require high writing endurance as they need to write data continually. In addition, as OTA (Over The Air Programming) function is added, faster writing speed is required to reduce the time taken for S/W upgrade.
MRAM delivers main benefits as the following
- Fast speed, Security feature
- Virtually no limit on endurance (100 trillion write cycle)
- Byte basis accessibility makes software more efficient. Smaller density required.
- Less program update time, Less power consumption (good for OTA)
- Safe from sudden power failure, Short recovering time
- Long data retention time (10years)

Industrial
Industrial applications normally require the prevention of data loss in harsh operating environments and long data retention. It also needs to ensure the data is backed-up quickly and safely at power failure, which is very critical for industrial applications.
MRAM is the most suitable memory for industrial applications as it can back up data quickly and safely even at power failure.
MRAM delivers main benefits as the following
- Eliminate voltage controller, battery and battery socket required for SRAM
- No capacitor for nvSRAM needed
- Safe from sudden power failure, Short recovering time
- Long retention time (10years)
- Security Features

Data Logging
Data Logging is a process of collecting and storing critical data over time.
The data is regarding :
– Events for tracking
– History of usage
– Environmental parameters
– Status of machine
– Other data for analyzing purpose
Fast write speed and high rewrite endurance are required for data logging memory.
MRAM delivers main benefits as the following
- No battery, no capacitor needed
- Fast write speed
- Virtually no limit on endurance (100 trillion write cycle)
- Immediate data back up at power failure

Gaming Machines
Gaming machines such as a slot machine and a Pachinko machine normally use battery-backed SRAM to store runtime processing data, machine states, configuration data and critical data (payout, number of winning outcome, player’s game record). These data should be kept even at power failure.
MRAM is an ideal back-up memory for gaming machines as it provides the unlimited write endurance, fast write and read cycles and doesn’t require a battery or a supercapacitor unlike SRAM.
MRAM delivers main benefits as the following
- Eliminate battery and battery socket
- Immediate back up at power failure
- Long retention time (10years)
- Virtually no limit on endurance (100 trillion write cycle)
- Fast write speed

Medical Devices
Portable ultrasound scanner detects the reflected sound waves from objects and turns them into real time images. It normally uses two memories : configuration memory and image/report memory.
Configuration memory is for storing identification and configuration information of outer hardware. And image/report memory is for storing images and corresponding report data. These data in both memories should be kept even at power failure.
MRAM is an ideal memory which can serve as both configuration memory and image/report memory as it prevent data loss at power failure.
MRAM delivers main benefits as the following
- Eliminate voltage controller, battery and battery socket required for SRAM
- No capacitor for nvSRAM needed
- Safe from sudden power failure, Short recovering time
- Long retention time (10years)
- Virtually no limit on endurance (100 trillion write cycle)
- Security Features

Enterprise Data Storage (RAID system)
RAID (Redundant Array of Inexpensive Disks) is a data storage structure of combining two or more physical storage devices (HDDs, SSDs) into a logical unit (an array) that is seen by the attached system as a single drive.
The journal memory in a RAID controller card stores log and critical data such as completion of data write, parity write, fail log, etc. At power failure, the controller refers to Journal memory and figures out where to start to recover, so data in the journal memory should be kept even at power failure. Battery-backed SRAM or nvSRAM is being used as journal memory.
As MRAM is a non-volatile memory and provides a fast write and real-time data storage, it is an ideal memory for RAID system.
MRAM delivers main benefits as the following
- Eliminate voltage controller, battery and battery socket required for SRAM
- No capacitor for nvSRAM needed
- Safe from sudden power failure, Short recovering time
- Long retention time (10years)
- Virtually no limit on endurance (100 trillion write cycle)
- Fast write speed
