Abstract:
1. A device, comprising: a verification voltage device that applies a verification voltage to a memory cell and analyzes impact of the verification voltage on the memory cell to facilitate determining a state change voltage to be applied to change a state of the memory cell; and a state-change voltage component that references a look-up table, determines the state-change voltage to apply to the memory cell in accordance with information relating to characteristics of the memory cell stored in the look-up table and the analyzed impact on the memory cell in response to the application of the verification voltage to the memory cell, wherein the state-change voltage is a safe amount of voltage as indicated in the look-up table such that when applied to the memory cell will cause minimal or no damage to the memory cell, and applies the voltage corresponding to the state change voltage to the memory cell in order to change the state of the memory cell.
