Abstract
Techniques and mechanisms to facilitate an operational mode of a memory device to prepare for a targeted refresh of a row in memory. In an embodiment, the memory device performs one or more operations while in the mode to prepare for a future command from a memory controller, the command to implement, at least in part, a targeted refresh of a row in a first bank of the memory device. Prior to such a command, the memory device services another command from the memory controller. In another embodiment, servicing the other command includes the memory device accessing a second bank of the memory device while the memory device operates in the mode, and before completion of an expected future targeted row refresh.
