* the same cell . Pairs are then indexed in ascending order .
*
* @ group is defining the position of a page in a given pair . It can also be

* group 0 , page attached to bit 1 belongs to group 1 , etc .
*
* Example :
* The H27UCG8T2BTR - BC datasheet describes the following pairing scheme :
*
* group - 0 group - 1
*
* pair - 0 page - 0 page - 4
* pair - 1 page - 1 page - 5
* pair - 2 page - 2 page - 8
* . . .
* pair - 127 page - 251 page - 255

*
* Note that the " group " and " pair " terms were extracted from Samsung and

* datasheets ( Micron is describing this concept as " shared pages " ) .
