Number of identical banks within Bank Region 1
(P+1B)h = 54h 00h (P+1B)h = 54h 00h
Number of program or erase operations allowed in
Bank region 1:
(P+1C)h = 55h 11h (P+1C)h = 55h 11h 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
(P+1D)h = 56h 00h (P+1D)h = 56h 00h _{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
(P+1E)h = 57h 00h (P+1E)h = 57h 00h 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
(P+1F)h = 58h 01h (P+1F)h = 58h 02h same-size erase blocks.
Symmetrically blocked banks have one blocking
region.⁽⁴⁾

(P+24)h = 5Dh 64h (P+24)h = 5Dh 64h _{Bank Region 1 (Erase Block Type 1)}
(P+25)h = 5Eh 00h (P+25)h = 5Eh 00h ^{Minimum block erase cycles × 1000}
Bank Region 1 (Erase Block Type 1): BIts per cell,
internal ECC
(P+26)h = 5Fh 01h (P+26)h = 5Fh 01h Bits 0-3: bits per cell in erase region
Bit 4: reserved for “internal ECC used”
BIts 5-7: reserved 5Eh 01 5Eh 01
Bank Region 1 (Erase Block Type 1): Page mode
and synchronous mode capabilities
Bit 0: Page-mode reads permitted
(P+27)h = 60h 03h (P+27)h = 60h 03h _{Bit 1: Synchronous reads permitted}
Bit 2: Synchronous writes permitted
Bits 3-7: reserved
