Abstract
A semiconductor device includes a data verification device. The data verification device includes a data storage unit for storing data to be input to a memory region in response to a first or second control signal, an input data verifier for deactivating an output of a sense amplifier in response to the first control signal and transmitting the input data stored in the data storage unit to an external pad, and a sense-amplifier verifier for transmitting the input data stored in the data storage unit to the sense amplifier upon in response to the second control signal.
Claims20
A data verification device comprising:
- a data storage unit configured to store input data in response to a first or second control signal generated in a test mode;
- an input data verifier configured to deactivate an output of a sense amplifier in response to the first control signal, and transmit the input data provided by the data storage unit to an external pad;
- and
- a sense-amplifier verifier configured to transmit the input data provided by the data storage unit to the sense amplifier in response to the second control signal, wherein the sense amplifier senses the input data transmitted thereto and transmits sensed data to the external pad.
A data verification device, comprising:
- a controller configured to generate a third control signal based on first and second control signals;
- a data storage unit configured to store input data in response to the third control signal;
- an input data verifier configured to deactivate an output of a sense amplifier in response to the third control signal and transmit the input data stored in the data storage unit to an external pad in a test mode;
- and
- a sense-amplifier verifier configured to transmit the input data stored in the data storage unit to the sense amplifier in response to the third control signal in the test mode, wherein the sense amplifier senses the input data transmitted thereto and transmits sensed data to the external pad.
A semiconductor device comprising:
- a core unit including a memory cell array;
- and
- a control unit configured to control data reading and writing operations within the semiconductor device,
- wherein the control unit includes:
- a data storage unit configured to store input data in response to a first or second control signal generated in a test mode;
- an input data verifier configured to deactivate an output of a sense amplifier in response to the first control signal, and transmit the input data provided by the data storage unit to an external pad;
- and
- a sense-amplifier verifier configured to transmit the input data provided by the data storage unit to the sense amplifier in response to the second control signal, wherein the sense amplifier senses the input data transmitted thereto and transmits sensed data to the external pad.
