Table 47: Partition Region 1 Information
Offset(1)
P = 39h
Description
Bottom Top
(Optional flash features and commands)
(P+1A)h (P+1A)h Number of identical partitions within the partition region
(P+1B)h (P+1B)h
(P+1C)h (P+1C)h Number of program or erase operations allowed in a partition
bits 0–3 = number of simultaneous Program operations
bits 4–7 = number of simultaneous Erase operations
(P+1D)h
(P+1E)h
(P+1F)h
(P+1D)h Simultaneous program or erase operations allowed in other
partitions while a partition in this region is in Program mode
bits 0–3 = number of simultaneous Program operations
bits 4–7 = number of simultaneous Erase operations
(P+1E)h Simultaneous program or erase operations allowed in other
partitions while a partition in this region is in Erase mode
bits 0–3 = number of simultaneous Program operations
bits 4–7 = number of simultaneous Erase operations
(P+1F)h Types of erase block regions in this Partition Region.
x = 0 = no erase blocking; the Partition Region erases in bulk
x = number of erase block regions w/ contiguous same-size
erase blocks. Symmetrically blocked partitions have one
blocking region. Partition size = (Type 1 blocks)x(Type 1
block sizes) + (Type 2 blocks)x(Type 2 block sizes) +…+
(Type n blocks)x(Type n block sizes)

(P+20)h Partition Region 1 Erase Block Type 1 Information
(P+21)h bits 0–15 = y, y+1 = number of identical-size erase blocks
(P+22)h bits 16–31 = z, region erase block(s) size are z x 256 bytes
(P+23)h
(P+24)h Partition 1 (Erase Block Type 1)
(P+25)h Minimum block erase cycles x 1000
(P+26)h Partition 1 (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” (1=yes, 0=no)
bits 5–7 = reserve for future use

(P+27)h Partition 1 (erase block Type 1) page mode and synchronous
mode capabilities defined in Table 10.
bit 0 = page-mode host reads permitted (1=yes, 0=no)
bit 1 = synchronous host reads permitted (1=yes, 0=no)
bit 2 = synchronous host writes permitted (1=yes, 0=no)
bits 3–7 = reserved for future use
Partition Region 1 Erase Block Type 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
(bottom parameter device only)
Partition 1 (Erase block Type 2)
Minimum block erase cycles x 1000
Partition 1 (Erase block Type 2) bits per cell
bits 0–3 = bits per cell in erase region
bit 4 = reserved for “internal ECC used” (1=yes, 0=no)
bits 5–7 = reserve for future use
Partition 1 (Erase block Type 2) pagemode and synchronous
mode capabilities defined in Table 10
bit 0 = page-mode host reads permitted (1=yes, 0=no)
bit 1 = synchronous host reads permitted (1=yes, 0=no)
bit 2 = synchronous host writes permitted (1=yes, 0=no)
bits 3–7 = reserved for future use
