For the case of page program
1) In section 3.2 it was explained that a number of consecutive partial program operations (NOP) is allowed within the
same page. In case this feature is used, the number of partial program operations occurring in the same EDC unit must
not exceed "one" (1). In other words, page program operations must be performed on the whole page, or on whole
EDC unit at a time.
2) "random data input" in a given EDC unit can be executed several times during one page program sequence, but data
insertion in each column address of each EDC unit must not exceed "one" (1).
For the case of copy back program
1) If random data input is applied in a given EDC unit, the data of the whole EDC unit must be inserted. In other words,
the EDC check is possible only if the whole EDC unit is modified during one copy back program sequence
2) "random data input" in a given EDC unit can be executed several times during one copy back sequence , but data
insertion in each column address of the EDC unit must not exceed "one" (1)
For the user which use Copy Back without EDC check, all the limitations described above do not apply.
