Micron SPI NOR Flash for PC BIOS
®
Finding a serial peripheral interface (SPI) NOR Flash solution
that’s right for your PC BIOS application is easy when you
have access to one of the industry’s broadest SPI NOR product
portfolios.
Our SPI NOR product line is tailored to meet PC BIOS application
requirements, including replay-protected monotonic counter
(RPMC)-based security needs. Your design will benefit from
dramatic read performance, flexible memory partitioning, small
package sizes, and a range of density and packaging options.
Meet Security Requirements
RPMC significantly enhances preboot security in cost-sensitive
embedded, mobile, and personal computing architectures. Our
RPMC-enabled device facilitates critical nonvolatile data storage
while making systems resistant to rollback and replay attacks. It
enables designers to strengthen code/data storage in the boot
memory and deliver increased security.
