System, apparatus and method for recovering link state during link training

Abstract:

In one embodiment, a link training controller is to train a link. The link training controller may be configured to: update a first link parameter of a link setting for the link to a first value; write data to the memory; read the data from the memory using the first value of the first link parameter; and in response to a determination that the data read from the memory does not match the data written to the memory, send an in-band link recovery command to the memory via the link to cause the memory to participate in a link recovery protocol with the apparatus. Other embodiments are described and claimed.
