Abstract:
A dynamic cache policy manager for a mass memory may be used to decide whether a data request is to be routed to the cache or directly to the mass memory, based on estimated delays in processing the request. The choice may be based, at least partially, on the size of the respectively queues for the cache and mass memory. For write requests, the choice may be based on how many erase blocks are available in the cache.
