Abstract
A memory device, and method of operation, includes an array of non-volatile memory cells and a controller. The controller is configured to perform an operation (e.g. erase, program, etc.) on a first plurality of the non-volatile memory cells using operational voltages with a first energy margin, and perform the same operation on a second plurality of the non-volatile memory cells using operational voltages with a second energy margin that is greater than the first energy margin. The operations of varying energy margins are based on the required storage longevity of the data being stored (lower energy margins for data being stored for shorter periods of time) to save energy and wear.
