Bad Blocks in NOR Flash Devices – KBA219740

Version: **

 

Question:

 How do I manage bad blocks in NOR flash devices? 

 

Answer:

There are no bad blocks to manage in any NOR flash, and the system does not need to provide ECC to correct bit errors for any NOR flash. 

Cypress Serial NOR and Parallel NOR flash always have 100 percent good blocks, and are suitable for executing code, reading binary data, and storing and retrieving data with very high reliability and excellent random-access speed.
