Device operations
6.9
Error detection code (EDC)
The EDC (error detection code) is performed automatically during all program operations. It
starts immediately after the device becomes busy.
The EDC detects 1 single bit error per EDC unit. Each EDC unit has a density of 528 bytes
(or 264 words), split into 512 bytes of main area and 16 bytes of spare area (or
256 + 8 words). Refer to Table 12 and Figure 20 for EDC unit addresses definition. EDC
results can only be retrieved during copy back program and multiplane copy back operations
using the Read EDC Status Register command (see Section 6.13: Read EDC status
To properly use the EDC, the following conditions apply:
Page program operations must be performed on a whole page, or on whole EDC unit(s)
The modification of the content of an EDC unit using a random data input before the
copy back program, must be performed on the whole EDC unit. It can only be done
once per EDC unit. Any partial modification of the EDC unit results in the corruption of
the on-chip EDCs.
