Abstract: The present invention provides a directory replacement method and device. An HA receives a data access request including a first address from a first CA, if a designated storage where a directory is located is entirely occupied by the directory, and a first directory entry corresponding to the first address is not in the directory, the HA selects a second directory entry from the directory, deletes it and adds the first directory entry into the directory; before the HA replaces the directory entry in the directory, no matter what status (for example, I status, S status or A status) a share status of a cache line corresponding to an address in the directory entry to be replaced is, the HA does not need to request a corresponding CA to perform an invalidating operation on data, but directly replaces the directory entry in the directory, thereby improving replacement efficiency.
