Abstract
A semiconductor system including a semiconductor device configured to operate in various modes to generate output data having different patterns.
Claims25
A semiconductor device comprising:
- a data processing circuit configured to receive an operation signal including a first combination of bits and generate internal data including the first combination of bits when the semiconductor device is operating in a serial mode, generate internal data including sequential bits including alternating logic values when the semiconductor device is operating in a clock mode, and generate internal data including a random combination of bits, the logic levels of which are generated randomly when the semiconductor device is operating in a random mode;
- and
- a memory circuit including a plurality of memory cells, and configured to store the internal data in the plurality of memory cells and generate output data from the stored internal data.
A semiconductor system comprising:
- a first semiconductor device configured to output a mode select signal, a code signal, and an operation signal, and receive output data;
- and
- a second semiconductor device configured to operate in a serial mode, a clock mode, and a random mode depending on the mode select signal and the code signal, generate internal data including a first combination of bits from the operation signal of which has the first combination of bits when operating in the serial mode, generate internal data including sequential bits including alternating logic values when operating in the clock mode, generate internal data including a random combination of bits, the logic levels of which are generated randomly when operating in the random mode, store the internal data, and output the internal data as the output data.
