Memory devices, circuits and methods having data values based on dynamic change in material property

Abstract

A method can include determining a data value stored in a memory element of a memory cell array based on the length of time required to cause a property of the memory element to change. A memory device can include a plurality of elements programmable into at least two different states; and an electrical bias section that applies sense conditions to a selected element; and a sense section configured to distinguish between the two different states according to whether a change in property occurs in the selected element within a predetermined time under the sense conditions.
