Abstract
A memory devices and methods can use multiple sense operations to detect a state of memory elements in a marginal state. In some embodiments, an evaluation circuit can generates an output value for a memory element in response multiple sense results for the same memory element. In other embodiments, a memory device can include both standard and strong read operations, where strong read operations apply more energy to a selected memory element than a standard read operation.
