Abstract
A memory includes an array of resistive memory cells and circuitry for setting a write parameter for improving write effectiveness to the cells of the memory array. The circuitry performs a write parameter setting routine that determines a midpoint resistance of a memory state of cells of the array and determines a write efficiency of a weak write operation to cells of the array. Based on the determined midpoint resistance and the determined write efficiency, the circuit sets a write parameter level for subsequent writes to cells of the array.
