Failure phenomena for Program and Erase operations
The following possible failure modes should be considered when implementing a highly reliable system.
•
•
Do not turn off the power before write/erase operation is complete. Avoid using the device when the battery
is low. Power shortage and/or power failure before write/erase operation is complete will cause loss of data
and/or damage to data.
The number of valid blocks is on the basis of single plane operations, and this may be decreased with two
plane operations.
The device may fail during a Program or Erase operation.
ECC: Error Correction Code. 1 bit correction per 512 Bytes is necessary.
Block Replacement
Program
Erase
(again by creating a table within the system or by using another appropriate scheme).
When an error occurs during an Erase operation, prevent future accesses to this bad block

When an error happens in Block A, try to reprogram the
data into another Block (Block B) by loading from an
external buffer. Then, prevent further system accesses
to Block A ( by creating a bad block table or by using
another appropriate scheme).
