Abstract
In one embodiment, the present invention includes a method for speculatively providing a read request to a memory controller associated with a processor, determining coherency of the read request in parallel with obtaining data of the speculatively provided read request, and providing the data of the speculatively provided read request to the processor if the read request is coherent. In this way, data may be used by a processor with a reduced latency. Other embodiments are described and claimed.
