– x16 data bus
• Program/erase suspend and resume capability
– Read from another block during a PROGRAM
SUSPEND operation
– Read or program another block during an ERASE
SUSPEND operation
• Unlock bypass, block erase, chip erase, and write to
buffer capability
• BLANK CHECK operation to verify an erased block
• CYCLIC REDUNDANCY CHECK (CRC) operation to
verify a program pattern
• VPP/WP# protection
– Protects first or last block regardless of block
protection settings
• Software protection
– Volatile protection
– Nonvolatile protection
– Password protection
