Abstract
A method of parity training for a dynamic random access memory, DRAM, is disclosed. The method comprises enabling a link error checking and correcting, ECC, functionality in a write operation of the DRAM, and remapping a parity function of a write parity pin to an data inversion function, a data replacing function, or a logical function, whereby data transferred to the DRAM through the write parity pin is used for indicating an inversion operation, a logical operation, or a substitution operation for data of a data pin.
