Notes
Unusable Sector
Initially, the M5M29F25611 contains unusable sectors.Due to the nature of the device architecture, the device
can also be screened and tested for partial invalid sectors for selected systems that can utilize the devices.
1. Tested for partial invalid sectors. The usable sectors were programmed the following data.
2. No erase and program for the partial invalid sectors by the system.
The device may fail during a program or erase operation due to program or erase cycle. The following
architecture will enable high system reliability if a failure occurs.
1. Error in read : Error correction that more than 3 bit error correction per each sector read is required for
data reliability.
2. Error in program or erase operation : The device may fail during a program or erase operation due to
program or erase cycle. The status register indicates that the program and erase operations are successfully
completed or not. After every program and erase operations, read status register to confirm
the program and erase operations are successfully completed.
When the error happens in sector, try to reprogram the data into another sector. Then, prevent further
system access to sector that error happens. Typically, recommended number of a spare sectors are 1.8%
within initial usable 16,057 sectors by each device.If the number of failed sectors exceed the number of the
spare sectors,usable data area in the device decreases.In the case of reprogramming to the spare sector ,do
not use the data from the failed sector.The reprogram data must be the data reloaded from outer buffer,or
use the Data recovery read mode or the Data recovery write mode(see the "Mode Description").To avoid
consecutive sector failurechoose addresses of spare sectors as far as possible from the failed sectors.
