Interface methods and apparatus for memory devices using arbitration

摘要

A disclosed example apparatus includes an interface (702, 726) to receive a request to access a memory (602a) of a memory module (600) and a data store status monitor (730) to determine a status of the memory. The example apparatus also includes a message output subsystem (732) to, when the memory is busy, respond to the request with a negative acknowledgement indicating that the request to access the memory is not grantable.

1. A memory module, comprising:
an interface to receive a request to access a memory of a memory module; a data store status monitor to determine a status of the memory; a message output subsystem to, when the memory is busy, respond to the request with a negative acknowledgement indicating that the request to access the memory is not grantable; and a data store access arbiter to, when the memory is busy, determine whether the request can be placed in a queue of the memory, the negative acknowledgment by the message output system being performed when the request cannot be placed in the queue.
