Abstract
A memory controller includes a command queue, an arbiter, and a controller. The controller is responsive to a repair signal for migrating data from a failing region of a memory to a buffer, generating at least one command to perform a post-package repair operation of the failing region, and migrating the data from the buffer to a substitute region of the memory. The controller migrates the data to and from the buffer by providing migration read requests and migration write requests, respectively, to the command queue. The arbiter uses the plurality of arbitration rules for both the read migration requests and the write migration requests, and the read access requests and the write access requests.
