Abstract
A semiconductor device may include an input control circuit, a counting circuit, an output control circuit, and a counting operation control circuit. The input control circuit may output a counting input signal based on an input signal and a counting over signal. The counting circuit may generate a preliminary counting code based on the counting input signal. The output control circuit may generate a counting code based on the preliminary counting code. The counting operation control circuit may generate the counting over signal based on a part of the counting code.
Claims16
A semiconductor device comprising:
- an input control circuit configured to output a counting input signal based on an input signal, an enabling signal, and a counting over signal;
- a counting circuit configured to generate a preliminary counting code based on a reset signal and the counting input signal;
- an output control circuit configured to generate a counting code based on the counting over signal and the preliminary counting code;
- and
- a counting operation control circuit configured to generate the counting over signal based on the reset signal and a part of the counting code.
A semiconductor device comprising:
- a counting circuit configured to count an input signal to generate a counting code,
- wherein the semiconductor device determines a set code value in response to a control signal, and fixes the counting code to a maximum value based on the counting code increasing to the set code value.
A semiconductor device comprising:
- an input control circuit configured to output a counting input signal based on an input signal and a counting over signal;
- a counting circuit configured to generate a preliminary counting code based on the counting input signal;
- an output control circuit configured to generate a counting code based on the preliminary counting code;
- and
- is a counting operation control circuit configured to generate the counting over signal based on a part of the counting code,
- wherein the counting operation control circuit enables the counting over signal to fix the counting input signal to a specific level to prevent the counting circuit from increasing a code value of the preliminary counting code.
