Abstract
A first group of memory cells of a memory device can be subjected to a particular quantity of program/erase cycles (PECs) in response to a programming operation performed on a second group of memory cells of the memory device. Subsequent to subjecting the first group of memory cells to the particular quantity of PECs, a data retention capability of the first group of memory cells can be assessed.
