After writing successfully a NAND block is this reliable ar reading as a NOR sector?


Hi,

Am interested in using MT29F2G08AABWP NAND Flash memory for a new embedded design and I couldn’t find a clear specification regarding how reliable is the NAND flash vs. NOR for reading operation.

If I program successfully a NAND block, read back and verify successfully the information and never erase or program that particular block again, can I assume that block will remain a good block and the information written there is safe for READING, roughly as safe as a NOR sector?

Thank you,
Andrei

Approximately, though NAND is subject to more bit-flipping than NOR. The ECC handling should make this transparent. See this whitepaper for additional information.
