Abstract
An apparatus, such as a memory (e.g., a NAND memory), can have a controller, a volatile counter coupled to the controller, and a non-volatile memory array coupled to the controller. The controller can be configured to write information, other than a count of the counter, in the array each time the count of the counter has been incremented by a particular number of increments. Counts can be monotonic, non-volatile, and power-loss tolerant.
