Reading of a nonvolatile memory cell by taking account of the stored state of a neighboring memory cell
Abstract
Shifts in the apparent charge stored on a floating gate (or other charge storage element) of a non-volatile memory cell can occur because of the coupling of an electric field based on the charge stored in adjacent floating gates (or other charge storing elements). To account for this coupling, the read process for a targeted memory cell will provide compensation to an adjacent memory cell (or other memory cell) in order to reduce the coupling effect that the adjacent memory cell has on the targeted memory cell. The compensation applied is based on a condition of the adjacent memory cell. To apply the correct compensation, the read process will at least partially intermix read operations for the adjacent memory cell with read operations for the targeted memory cell.
