Abstract
A nonvolatile memory controller and a method for erase suspend management are disclosed. The nonvolatile memory controller includes an erase suspend circuit configured for determining a pre-suspend time each time that an erase operation of the nonvolatile memory device is suspended and for determining whether an erase-suspend limit has been reached using the determined pre-suspend time. The erase suspend circuit is further configured for incrementing the number of program and erase cycles when the erase-suspend limit has been reached.
