Abstract:
A system may include multiple memory cells to store logical data, age tracking circuitry to track a time since a previous access of a particular memory cell, and control circuitry to access the memory cell. Such access may include a read operation of the memory cell, a write operation to the memory cell, or both. The control circuitry may determine an electrical parameter of the memory cell based at least in part on the tracked time since the previous access of the memory cell.
