Methods for performing a memory resource retry

Abstract:

In an embodiment, an apparatus includes multiple memory resources, and a resource table that includes entries that correspond to respective memory resources of the multiple memory resources. The apparatus also includes a circuit configured to receive a first memory command. The first memory command is associated with a subset of the multiple memory resources. For each memory resource of the subset, the circuit is also configured to set a respective indicator associated with the first memory command, and to store a first value in a first entry of the resource table in response to a determination that the respective memory resource is unavailable. The circuit is also configured to store a second value in each entry of the resource table that corresponds to a memory resource of the subset in response to a determination that an entry corresponding to a given memory resource of the subset includes the first value.
