A memory subsystem includes a memory coupled to a memory controller. The memory controller may operate in one of a number of different performance states. The memory controller further includes a calibration circuit configured to perform reference voltage calibrations for the various ones of the performance states to determine corresponding reference voltages. For a performance state change from an initial performance state to a final performance state, via an intermediate performance state, the memory controller is configured to transition to the intermediate performance state without causing the calibration circuit to perform a reference voltage calibration in that state. Thereafter, the memory controller transitions to the final performance state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Selective reference voltage calibration in memory subsystem","description":"A method and apparatus for selective reference voltage calibration in a memory subsystem is disclosed.
