Abstract
In a data processing system, a memory subsystem detects whether or not at least one potentially transient condition is present that would prevent timely servicing of one or more memory access requests directed to the associated system memory. In response to detecting at least one such potentially transient condition, the memory system identifies a first read request affected by the at least one potentially transient condition. In response to identifying the read request, the memory subsystem signals to a request source to issue a second read request for the same target address by transmitting to the request source dummy data and a data error indicator.
