Programmable and flexible reference cell selection method for memory devices

A method of conditioning a reference array, comprising:

• receiving an input;
• generating a selection signal, based on the input and one or more characteristics of a reference array of interconnected reference sources;
• providing the selection signal to the reference array, wherein the reference array provides a reference current or voltage as output corresponding to the selection signal;
• repeating the receiving, generating, and providing steps for a plurality of inputs to determine a relationship between the inputs and their respective output currents or voltages;
• and
• changing the generation of selection signals so as to change the relationship between the plurality of inputs and their respective output currents or voltages.

A method, comprising:

• receiving an input;
• generating, based on the input and one or more characteristics of a reference array of interconnected reference sources, a selection signal;
• and
• providing the selection signal to the reference array, wherein the reference array provides a reference current or voltage as output corresponding to the selection signal.

A non-transitory computer readable storage medium having program instructions stored thereon that, when executed by a processor, cause the processor to perform operations, the operations comprising:

• receiving an input;
• generating a selection signal based on the input;
• and
• providing the selection signal to a reference array of interconnected reference sources to cause the array to provide a reference current or voltage as output.
