The invention provides a chip restoration method and device and aims at solving the problems that data which are finally read out of a chip are wrong due to the fact that an EEC area of the chip cannot be restored, and chip resources are low in utilization rate. The method comprises the steps of obtaining first address information of a storage unit which is faulted in a main array and second address information of a storage unit which stores error coding correction redundancy bits and is faulted; mapping the first address information and the second address information to address information of redundancy resources respectively, and restoring the chip. By means of the chip restoration method and device, the main array and the EEC area can be restored simultaneously, the chip reliability is improved, and the product yield rate is further raised. The second address information is mapped to the address information of the redundancy resources, the redundancy resources are utilized sufficiently, and the utilization rate of the chip resources is raised.
