Abstract
A method for processing a read request identifying an address. The method includes receiving, at a module including a flash memory and a memory buffer, the read request from a requesting processor, mapping, using a coherence directory controller within the module, the address to a cache line in a cache memory associated with a remote processor, and sending a coherency message from the module to the remote processor to change a state of the cache line in the cache memory. The method further includes receiving, at the module, the cache line from the remote processor, sending, using processor bus and in response to the read request, the cache line to the requesting processor, identifying a requested page stored within the flash memory based on the address, storing a copy of the requested page in the memory buffer, and writing the cache line to the copy of the requested page.
