Primary-Vendor Specific Extended Query Table
Certain flash features and commands are optional. The
Primary Vendor-Specific Extended Query
table specifies this and other similar information.

Number of erase block regions within device:
1. x = 0 means no erase blocking; the device erases in “bulk”
2. x specifies the number of device or partition regions with one or
more contiguous same-size erase blocks
3. Symmetrically blocked partitions have one blocking region
4. Partition size = (total blocks) x (individual block size)
Erase Block Region 1 Information
bits 0–15 = y, y+1 = number of identical-size erase blocks
bits 16–31 = z, region erase block(s) size are z x 256 bytes
