System Bad Block Replacement
Over the lifetime of the device, additional Bad Blocks may develop. In this case, each bad block has to be
replaced by copying any valid data to a new block. These additional Bad Blocks can be identified whenever a
program or erase operation reports “Fail” in the Status Register.
The failure of a page program operation does not affect the data in other pages in the same block, thus the
block can be replaced by re-programming the current data and copying the rest of the replaced block to an
available valid block. Refer to
occurs during an operation.
Notes:
1. An error occurs on the Nth page of Block A during a program operation.
2. Data in Block A is copied to the same location in Block B, which is a valid block.
3. The Nth page of block A, which is in controller buffer memory, is copied into the Nth page of Block B.
4. Bad block table should be updated to prevent from erasing or programming Block A.
