SEMICONDUCTOR APPARATUS |
摘要 |
A semiconductor apparatus includes a command decoding unit configured to decode an internal command, an internal clock and an internal clock enable signal, and generate an internal control signal; a clock enable signal control unit configured to receive a pre-clock enable signal and output one of the pre-clock enable signal and an enabled internal clock enable signal as the internal clock enable signal in response to a first test signal; an enable signal selection unit configured to output one of the pre-clock enable signal and a second to test signal as a counting enable signal in response to the first test signal; and a counting unit configured to perform a counting operation during an enable period of the counting enable signal, and output a counting code. |
