摘要: A semiconductor apparatus includes a command decoding circuit and an enable signal generation circuit. The command decoding circuit generates a plurality of operation codes and a strobe pulse based on a command signal and a clock signal. The enable signal generation circuit generates a seed signal based on at least a part of an operation code, among the plurality of operation codes, and the strobe pulse, and generates an enable signal by shifting the seed signal. The enable signal generation circuit generates a plurality of guard keys, after the seed signal is generated, based on the plurality of operation codes and the strobe pulse, and prevents the generation of the enable signal when any one of the plurality of guard keys is disabled.

摘要: A semiconductor device includes an input/output (I/O) control signal generation circuit, a pipe circuit and an auto-pre-charge signal generation circuit. The I/O control signal generation circuit generates an input control signal, an output control signal and an internal output control signal. The pipe circuit latches an internal command/address signal based on the input control signal and outputs the latched internal command/address signal as a latch signal. The auto-pre-charge signal generation circuit generates an auto-pre-charge signal from the latch signal and the internal latch signal.

摘要: A semiconductor apparatus may include a synchronization circuit, and a phase detection circuit. The synchronization circuit may be configured to, based on an operation mode of the semiconductor apparatus, divide a first clock signal to generate first and second divided clock signals or divide a phase-locked clock signal to generate first and second divided clock signals. The phase detection circuit may be configured to use, based on the operation mode of the semiconductor apparatus, either the first and second clock signals created from dividing the first clock signal or the first and second clock signals created from dividing the phase-locked clock signal, to compare either the first divided clock signal or the second divided clock signal with a second clock signal to generate a phase detection signal.

摘要: A device includes an operation control circuit and a drive control signal generation circuit. The operation control circuit generates an internal refresh signal that is activated to perform an active operation for a cell array, the cell array being coupled to a word line that is selected by a row address based on a refresh signal that is activated to perform a refresh operation. In addition, the operation control circuit generates a pre-refresh pulse based on the refresh signal and generates a refresh end pulse based on the internal refresh signal. The drive control signal generation circuit generates a drive control signal to control a drive of an active voltage that is supplied to the word line that is selected by the row address based on the internal refresh signal, the pre-refresh pulse, and the refresh end pulse.
