Abstract
An apparatus includes one or more control circuits that are configured to connect to a plurality of nonvolatile memory cells. The one or more control circuits are configured to detect a first boundary between written and unwritten portions of an open block and, in response to detecting the first boundary, check for a second boundary between written and unwritten portions of the open block in order to determine if the open block was subject to a non-uniform erase operation.
