APPARATUS, METHOD AND SYSTEM FOR DETERMINING REFERENCE VOLTAGES FOR A MEMORY

摘要

Techniques and mechanisms for a memory device to concurrently receive and process signals each based on a different respective reference voltage level. In an embodiment, an input/output (I/O) interface of a memory device includes receiver circuits each to process a respective signal received via a corresponding signal line of a bus. In response to one or more configuration commands, a first receiver circuit is configured to process a first signal based on a first reference voltage level and a second receiver circuit is configured to process a second signal based on a second reference voltage level. In another embodiment, a memory controller sends the one or more configuration commands to such a memory device based on an evaluation of voltage swing characteristics each corresponding to a different respective signal line of a bus.
