Abstract
There is provided a method of executing a multiplication and accumulation (MAC) calculation in a PIM device. The method may include outputting first data and a parity from a first storage region, outputting second data from a second storage region, simultaneously executing an error correction code (ECC) calculation of the first data and the parity and a multiplying calculation of the first and second data, generating an error code indicating an error location of the first data as a result of the ECC calculation, outputting multiplication result data corresponding to a result of the multiplying calculation when no error exists in the first data based on the error code, and executing a compensating calculation of the multiplication result data to output the compensated multiplication result data when an error exists in the first data based on the error code.
