4.5.5 SCS OEM Specific Extended Query Table

Certain flash features and commands may be optional in a vendor-specific algorithm specification. The optional

vendor-specific Query table(s) may be used to specify this and other types of information. These structures are

defined solely by the flash vendor(s).
