Abstract
A memory includes a memory array and a read control circuit configured to effectuate a read operation of a memory cell in the array. The read control circuit is configured so that the read operation contemplates one or more drift conditions associated with the memory cell. A method of reading a memory cell is also disclosed and includes detecting one or more drift conditions of a memory cell, and setting one or more read reference levels based on the one or more detected drift conditions. The memory cell is then read using the set one or more read reference levels.
