(P+33)h = 13Dh 00h (P+3B)h = 145h 00h
Number of identical banks within bank region 2
Number of program or erase operations allowed in
bank region 2:
(P+34)h = 13Eh 11h (P+3C)h = 146h 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 this region is
programming
(P+35)h = 13Fh 00h (P+3D)h = 147h 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+36)h = 140h 00h (P+3E)h = 148h 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 2
n = number of erase block regions with contiguous
(P+37)h = 141h 02h (P+3F)h = 149h 01h same-size erase blocks.
Symmetrically blocked banks have one blocking
region.(2)
(P+38)h = 142h 0Eh (P+40)h = 14Ah 0Fh
(P+39)h = 143h 00h (P+41)h = 14Bh 00h
(P+3A)h = 144h 00h (P+42)h = 14Ch 00h
(P+3B)h = 145h 02h (P+43)h = 14Dh 02h
(P+3C)h = 146h 64h (P+44)h = 14Eh 64h
(P+3D)h = 147h 00h (P+45)h = 14Fh 00h
Bank region 2 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
Bank region 2 (Erase Block type 1)
Minimum block erase cycles × 1000
Bank region 2 (Erase Block type 1): bits per cell,
internal ECC
Bits 0-3: bits per cell in erase region
Bit 4: reserved for “internal ECC used”
Bits 5-7: reserved
(P+3E)h = 148h 02h (P+46)h = 150h 02h
Bank region 2 (Erase Block type 1): page mode
and synchronous mode capabilities (defined in
Table 41)
Bit 0: page-mode reads permitted
Bit 1: synchronous reads permitted
Bit 2: synchronous writes permitted
Bits 3-7: reserved
(P+3F)h = 149h 03h (P+47)h = 151h 03h
