Abstract:
Various aspects of a nonvolatile memory have an improved erase suspend procedure. A bias arrangement is applied to word lines of an erase sector undergoing an erase procedure interrupted by an erase suspend procedure. As a result, another operation performed during erase suspend, such as a read operation or program operation, has more accurate results due to decreased leakage current from any over-erased nonvolatile memory cells of the erase sector.
