Abstract
A nonvolatile memory block experiences multiple write-erase cycles during which data is subject to a shaping operation prior to storage. In response to a write-erase cycle count reaching a predetermined number, a polling cycle occurs during which shaping is disabled and data is collected that indicates a condition of the block. Subsequently, shaping is reenabled for subsequent cycles.
