Device Geometry Definition
“n” such that typical max. buffer write time-out = 2
“n” such that typical block erase time-out = 2
“n” such that typical full chip erase time-out = 2
“n” such that maximum word program time-out = 2
“n” such that maximum buffer write time-out = 2
“n” such that maximum block erase time-out = 2
“n” such that maximum chip erase time-out = 2
“n” such that device size = 2
Flash device interface:
“n” such that maximum number of bytes in write buffer = 2
Number of erase block regions within device:
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
Erase Block Region 2 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
1. x = 0 means no erase blocking; the device erases in “bulk”
2. x specifies the number of device or partition regions
3. Symmetrically blocked partitions have one blocking region
4. Partition size = (total blocks) x (individual block size)
with one or more contiguous same-size erase blocks.
