The present invention relates to a dynamic built-in self-skip method used for shared memory fault recovery. The method employs the mapping relationship between the packet buffer and free link table under the shared memory structure. First, we record the blocks in the free link table corresponding to the defective rows in the packet buffer without carrying out initialization to the blocks recorded as fail, so that they do not enter the package switching activity. Therefore the defective rows of the memory mapping to fail blocks do not proceed with the read/write process, in other words, accomplishing the object of fault recovery. The recovery method is not dependent on the memory architecture and complex algorithms, and thus it may be easily associated with designs of various systems and increases chip yield.
