(P+1A)h = 53h 0Fh (P+1A)h = 53h 01h 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 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

(P+1D)h = 56h 00h (P+1D)h = 56h

00h

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

(P+1E)h = 57h

00h (P+1E)h = 57h

00h

while a bank in this region is erasing

Bits 0-3: Number of simultaneous program operations

Bits 4-7: Number of simultaneous erase operations

(P+1F)h = 58h 01h (P+1F)h =58h

Types of erase block regions in region 1

n = number of erase block regions with contiguous same-size

02h erase blocks.

Symmetrically blocked banks have one blocking region.(2)

(P+20)h = 59h 07h (P+20)h = 59h 07h

(P+21)h = 5Ah 00h (P+21)h = 5Ah 00h Bank Region 1 Erase Block Type 1 Information

Bits 0-15: n+1 = number of identical-sized erase blocks

(P+22)h = 5Bh 00h (P+22)h = 5Bh 20h Bits 16-31: n×256 = number of bytes in erase block region

(P+23)h = 5Ch 01h (P+23)h = 5Ch 00h

(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

(P+27)h = 60h

03h (P+27)h = 60h

03h

Bit 0: Page-mode reads permitted

Bit 1: Synchronous reads permitted

Bit 2: Synchronous writes permitted

Bits 3-7: reserved
