Abstract
A semiconductor system may be provided. The semiconductor system may include a fail information generator and a data mapping circuit. The fail information generator may detect a data fail address of a data storage region. The data mapping circuit may change a mapping table based on the data fail address, and transmit data to be stored at the data fail address in the data storage region, to a parity storage region.
Claims6
A semiconductor system comprising:
- a fail information generator configured to detect a data fail address of a data storage region;
- a mapping table logic configured to change a mapping table based on the data fail address;
- a data mapper configured to transmit data to be stored at the data fail address, to a parity storage region, based on the mapping table;
- and
- a read and write (read/write) controller configured to causes a value of the mapping table to be provided to the data mapper after a time corresponding to one of a write latency and a read latency passes, based on a command signal and an address.
