Why Replace a Battery-Backed SRAM with MRAM?

Because an MRAM is a fast Read/Write memory that is inherently non-volatile - without requiring any additional components.

BBSRAM (Battery-Backed SRAM)

BBSRAM or Battery-Backed SRAM is an SRAM memory that is backed up with a lithium battery to maintain the power supply voltage on the memory and preserve data in the event of an unintentional power failure.

  • Not RoHS compliant. Battery disposal is a concern.
  • Significant system space and BOM cost.

Magnetoresistive RAM (MRAM)

MRAM is inherently non-volatile, with unlimited endurance for stored data, even when power is lost.

  • SRAM compatible. Equal or better Read/Write cycle times.
  • Unlimited Read and Write Endurance.
  • Data non-volatile for greater than 20 years.
  • RoHS compliant.
  • Commercial, Industrial, Automotive temperature options.
