Description
Primary Micron-specific extended query Vendor-defined informaton specific to the primary vendor
algorithm (offset 15 defines P which points to the primary
Micron-specific extended query table)
CFI ID String
The CFI ID string provides verification that the device supports the CFI specification. It
also indicates the specification version and supported vendor-specific command sets.
