Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified strictly as NOR flash without EEPROM functionality
Customs may classify advanced flash memories under 'other memories' if erase mechanisms don't meet traditional EEPROM definitions.
If when part of computer memory modules
EEPROMs assembled into DIMMs or SO-DIMMs for computers fall under parts and accessories of automatic data processing machines.
If EEPROM used in instrument calibration memory
ICs specifically for measurement instrument memory may be classified as parts of instruments/apparatus rather than general ICs.

Import Tips & Compliance
• Confirm SPI interface specs and sector erase times in documentation; distinguish from pure NAND flash (other classifications); ensure JEDEC standard compliance for interoperability
