Abstract
A method of adjusting a resistive change element using a reference is disclosed. The method comprises inspecting a resistive change element to determine a first state; comparing the first state to a reference wherein said reference provides stimulus parameters corresponding to a transition from the first state to a second state; and applying the stimulus parameters to the resistive change element. A resistive change memory cell array is also disclosed.
Claims35
A method of adjusting the resistance of a non-volatile resistive change element from a first state to a desired second state, comprising:
- inspecting a resistive change element to determine a first state;
- determining if said first state is distinct from a desired second state;
- selecting a set of stimulus parameters from a pre-generated list of stimulus parameter sets, wherein said selected set of stimulus parameters are selected in response to said determined first state and said desired second state and correspond to a transition from said determined first state to said desired second state, when said determined first state is distinct from said desired second state;
- and
- applying said selected set of stimulus parameters to said resistive change element, when said determined first state is distinct from said desired second state.
