Abstract
A system for operating a memory device includes a memory array having a number of memory cells and a set of dynamic reference cells coupled to the memory cells in word lines. Each of the dynamic reference provides the associated memory cells with a dynamic reference value for determining a status of at least one of the associated memory cells. The dynamic reference value is capable of reflecting a variation in a threshold value of at least one of the associated memory cells.
