Abstract
The invention provides circuits, systems, and methods for monitoring a non-volatile memory (NVM) cell, or an array of NVM cells. The monitor is capable of switching from a normal operating state to an evaluation state, monitoring for one or more particular characteristics, and returning to the normal operating state. Alternative embodiments of the invention are disclosed using various triggers and producing outputs capable of reporting or feeding back to influence the operation of the monitoring systems and methods, the NVM circuitry, or an external system. The invention includes an energy conservation feature, in that no power is consumed in the normal operating state, and low power in the evaluation state.
