MRAM eliminates the need for storage capacitors when data logging, increases product longevity and system reliability while reducing TCO.

Engine control units, infotainment systems, power seat controllers, power steering units, brake management systems, robotic manufacturing equipment, industrial controls all have one thing in common; each of these designs must store logged data when power is interrupted, lost or turned off.

Storage capacitors are generally used to keep the entire system powered when data must be transferred from volatile memory
to non-volatile memory (FLASH or EEPROM are generally used). Non-volatile MRAM (Magneto-resistive RAM) eliminates the need for this effort because storing data in MRAM is always fast and non-volatile.

With SRAM and SPI interfaces (i.e. no unique voltages, no unique commands), fast write speeds, unlimited endurance, 20 year data retention and automotive temperature ranges, MRAM is the ultimate solution for storing data. With the speed and unlimited endurance of SRAM yet non-volatility of FLASH, designing with MRAM eliminates designing products for a limited lifetime. Storing more data more often provides better system performance and ultimately a better product to your customer. And when storage capacitors are eliminated, system reliability increases and total cost of ownership is reduced.

When a power fail is detected, a system goes into panic mode!
• Critical data must be saved before power level is too low
The data backup process when power is failing is the ‘Achilles heel’
MRAM can save the data very quickly
• MRAM replaces the “Persistent RAM” or “High Integrity NVM” system
• Data gets committed to memory faster
• MRAM has the fastest write speed of any NV memory

DATA LOGGING

  • Store data only once in a non-volatile memory when the data is sampled
  • No need to transfer from volatile memory to non-volatile memory when power is lost
  • Eliminates the need for super capacitors
  • Increases reliability
  • Reduces system cost
