Abstract

See full text

A semiconductor system may include a first semiconductor device and a second semiconductor device. The first semiconductor device may be configured to output command/address signals. The second semiconductor device may be configured to output data in a read operation during a refresh operation according to a combination of the command/address signals. The second semiconductor device may be configured to extract error information from the data. The second semiconductor device may be configured to corrects errors of the data using the error information in a write operation during the refresh operation to store the corrected data in the second semiconductor device and to store the error information in the second semiconductor device.
