Description
Number of identical banks within Bank Region 2
Number of program or erase operations allowed in Bank Region 2:
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
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 2 n = number of erase block regions with
contiguous same-sized erase blocks. Symmetrically blocked banks have one blocking
region.⁽²⁾
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
Bank Region 2 (Erase Block Type 1):Page mode and Synchronous mode capabilities (defined
in Table 42, page 68)
Bit 0: Page-mode reads permitted
Bit 1: Synchronous reads permitted
Bit 2: Synchronous writes permitted
Bits 3–7: reserved

Notes:
1. The variable P is a pointer which is defined at CFI offset 015h.
2. Bank Regions. There are two Bank Regions, see Table 35, page 61.
