Abstract
A semiconductor apparatus may include an internal voltage level controller configured to output either a normal trimming code or a test voltage code as a voltage control code in response to a test mode signal, a specific operation start signal, and a specific operation end signal. The semiconductor apparatus may include an internal voltage generator configured to generate an internal voltage and control a voltage level of the internal voltage in response to the voltage control code.
Claims9
A semiconductor apparatus comprising:
- an internal voltage level controller configured to output either a normal trimming code or a test voltage code as a voltage control code in response to a test mode signal, a specific operation start signal, and a specific operation end signal;
- and
- an internal voltage generator configured to generate an internal voltage in response to the voltage control code,
- wherein the specific operation start signal is an active pulse, and the specific operation end signal is a precharge pulse.
