Abstract
Apparatuses supporting multiple interface types and methods operating the same are described. One such method can include providing, to a memory device, a first input/output (I/O) supply voltage corresponding to a first interface type and subsequently determining whether the memory device supports a second interface type having a second I/O supply voltage corresponding thereto. In response to a determination that the memory device supports the second interface type, the method can include adjusting the I/O supply voltage provided to the memory device from the first I/O supply voltage to the second I/O supply voltage.

A method, comprising:
- providing, to a memory device, a first input/output (I/O) supply voltage corresponding to a first interface type;
- subsequently determining whether the memory device supports a second interface type having a second I/O supply voltage corresponding thereto;
- and
- adjusting the I/O supply voltage provided to the memory device from the first I/O supply voltage to the second I/O supply voltage in response to a determination that the memory device supports the second interface type.
