Invalid Block Table Creation Flow Chart
Within its life time, additional invalid blocks may develop with NAND Flash Array memory. Refer to the device's qualification report for
the actual data.
The following possible failure modes should be considered to implement a highly reliable system.
In the case of a status read failure after erase or program, a block replacement should be done. Because program status failure
during a page program does not affect the data of the other pages in the same block, a block replacement can be executed with a
page-sized buffer by finding an erased empty block and reprogramming the current target data and copying the rest of the replaced
block.
