Abstract
In response to a write operation on a storage element in a non-volatile memory device, a count provided by a global counter is stored to indicate a time at which the write operation occurs on the storage element. In response to receiving a request perform a read operation on the storage element, a determination is made of a demarcation voltage to apply for performing the read operation on the storage element, based on a progress of the global counter since the write operation on the storage element.
