Number of identical banks within bank region 1
Number of program or erase operations allowed in
bank region 1:
Bits 0-3: number of simultaneous program
operations
Bits 4-7: number of simultaneous erase
operations
Number of program or erase operations allowed in
other banks while a bank in same region is
programming
Bits 0-3: number of simultaneous program
operations
Bits 4-7: number of simultaneous erase
operations
Number of program or erase operations allowed in
other banks while a bank in this region is erasing
Bits 0-3: number of simultaneous program
operations
Bits 4-7: number of simultaneous erase
operations
Types of erase block regions in bank region 1
n = number of erase block regions with contiguous
same-size erase blocks.
Symmetrically blocked banks have one blocking
region
Bank Region 1 Erase Block Type 1 Information
Bits 0-15: n+1 = number of identical-sized erase
blocks
Bits 16-31: n×256 = number of bytes in erase
block region
