Abstract
A memory module includes a memory, a cache to cache copies of information stored in the memory, and a controller. The controller is configured to access first data from the memory or the cache in response to receiving a read request from a processor. The controller is also configured to transmit a first signal a first nondeterministic time interval after receiving the read request. The first signal indicates that the first data is available. The controller is further configured to transmit a second signal a first deterministic time interval after receiving a first transmit request from the processor in response to the first signal. The second signal includes the first data. The memory module also includes a buffer to store a write request until completion and a counter that is incremented in response to receiving the write request and decremented in response to completing the write request.
