Abstract
An array of memory cells having a predetermined group of storage cells, arranged in a row, also have an arrangement of one or more reference cells fabricated to be adjacent to or proximate to the row of storage cells. The reference cells are written to, erased, or programmed when the storage cells are written to, erased, or programmed. The same number of write, erase, or program cycles and the proximity of the reference cells to the storage cells maintain an operational matching of the storage cells and reference cells.
