Methods of configuring a system. More specifically, operating current values corresponding to respective memory devices of memory module may be stored in programmable elements, such as antifuses, located on the memory device, during fabrication. The operating current values may be read from and/or stored in a non-volatile memory device on the memory module. Once the memory module is incorporated into a system, the programmable elements on the memory devices and/or the non-volatile memory device on the memory module may be accessed such that the system can be configured to optimally operate in accordance with the operating current values measured for each memory device in the system.
