ABSTRACT:
A memory cell with a charge storage structure is read by measuring current between the substrate region of the memory cell and one of the current carrying nodes of the memory cell. The read operation decreases the coupling between different parts of the charge storage structure when other parts of the charge storage structure store data that are not of interest. The sensing window of the memory cell can be greatly improved by this read operation. Example arrangements are a series of memory cells, and an array of series of memory cells.
