Assignee: MICRON TECHNOLOGY, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 19:
20. A method of operating a semiconductor device, the method comprising:
accessing a setting representative of a communication setting for the semiconductor device; and
according to the accessed setting, selectively controlling one or more components of the semiconductor device to select (1) a multi-drop communication configuration or a point-to-point communication configuration, (2) an input communication path and/or an output communication path, (3) a terminated path or a non-terminated path, (4) a single-ended communication configuration or a complementary communication configuration, or a combination thereof for communicated signals, wherein selectively controlling the one or more components includes:
controlling an operating state of an output buffer configured to generate output signals based on a variable driver voltage, wherein controlling the operating state includes activating or deactivating a pull-up driver and a pull-down driver;
setting the variable driver voltage to a system voltage, an intermediate voltage less than the system voltage, or an open circuit setting for generating the output signals;
controlling an operating state of an input buffer configured to receive input signals from an external circuit according to a variable reference; and
setting the variable reference to provide a reading range up to the system voltage or up to a reduced voltage for receiving the input signals.
