Abstract
A method includes storing data values in a group of memory cells that share a common isolating layer, by producing quantities of electrical charge representative of the data values at respective regions of the common isolating layer that are associated with the memory cells. A function, which relates a drift of the electrical charge in a given memory cell in the group to the data values stored in one or more other memory cells in the group, is estimated. The drift is compensated for using the estimated function.
