Internal voltage generation circuit and method for semiconductor device
An internal voltage generation circuit for a semiconductor device and method therefor includes a voltage generator configured to generate voltages with different levels by using an external voltage. A code storing unit is configured to store a selection code to select an internal voltage out of the plurality of voltages. A decoding unit selects the internal voltage from among the plurality of voltages in response to the selection code in a normal mode, and selects the internal voltage out of the plurality of voltages in response to a test selection code set in a test mode. The interval voltage selected in the normal mode is used as an initial value that is a reference of the selection in the test mode.
