Abstract

A non-volatile memory system may include detection circuitry configured to detect that a host system is configured to initially communicate a clock signal and initialization command signals at a voltage level lower than its input/output driver circuit is configured to receive the signals. In response to the detection, the detection circuitry may switch a regulator circuit from a high voltage mode to a low voltage mode so that the input/output driver circuit is ready to receive the initialization commands at the lower voltage level.
