Abstract
An electronic device includes a pattern data generation circuit and a data input/output (I/O) circuit. The pattern data generation circuit generates pattern data having a serial pattern based on a command/address signal. The data I/O circuit outputs the pattern data or read data as internal data based on a read command for a read operation and an internal command in a test mode. The data I/O circuit receives and stores the internal data, which are output, as write data for a write operation.
