   - Sector Erase(sector structure: eight 64 KB)
• Auto Erase (chip & sector) and Auto Program
   - Any combination of sectors can be erased
      concurrently; Chip erase also provided.
   - Automatically program and verify data at specified
      address
• Erase Suspend/Erase Resume
   - Suspend or Resume erasing sectors to allow the
      read/program in another sector
• End of program or erase detection
   - Data polling
   - Toggle bits
• Sector Protection /Un-protection
   - Hardware Protect/Unprotect any combination of sectors
      from a program or erase operation.
• Low VCC Write inhibit is equal to or less than 2.0V
