  • Patent number: 9239755
    Abstract: A semiconductor system includes a memory configured to output a parity bit during a read operation and receive a data mask (DM) signal during a write operation. The semiconductor system also includes a System On Chip (SOC) configured to detect errors by decoding the parity bit during the read operation, and output the DM signal to the memory during the write operation. Since the parity bit is generated in the memory based on data received from outside the memory, the semiconductor device and a corresponding semiconductor system may reduce the size of a storage space for parity bits.
