CELL-STATE DETERMINATION IN PHASE-CHANGE MEMORY |
摘要 |
<p>A method, an apparatus, and a device for determining the state of a phase-change memory cell. The method includes the steps of: biasing a cell with a time-varying read voltage (Vread); making a measurement (TM) that satisfies a predetermined condition where the predetermined condition depends on a cell current when the read voltage is applied; and determining a state of the cell based on the measurement.</p> |
