By way of example, a memory access handler is provided for managing memory access requests and determining associated priorities. The memory access handler includes logic configured for propagating memory requests and the associated priorities to lower levels of a computer hierarchy. A memory subsystem receives the memory access requests and the priorities.

Abstract: Systems and methods are provided that facilitate memory storage in a memory device. The system contains a memory controller and a memory array communicatively coupled to the memory controller. The memory controller sends commands to the memory array and the memory array writes or retrieves data contained therein based upon the command. The memory controller can monitor multiple banks and manage bank activations. Accordingly, memory access overhead can be reduced and memory devices can be more efficient.

Abstract: Various aspects provide for managing data associated with a cache memory. For example, a system can include a cache memory and a memory controller. The cache memory stores data. The memory controller maintains a history profile for the data stored in the cache memory. In an implementation, the memory controller includes a filter component, a tagging component and a data management component. The filter component determines whether the data is previously stored in the cache memory based on a filter associated with a probabilistic data structure. The tagging component tags the data as recurrent data in response to a determination by the filter component that the data is previously stored in the cache memory. The data management component retains the data in the cache memory in response to the tagging of the data as the recurrent data.

Abstract: Various embodiments provide for a system that prefetches data from a main memory to a cache and then evicts unused data to a lower level cache. The prefetching system will prefetch data from a main memory to a cache, and data that is not immediately useable or is part of a data set which is too large to fit in the cache can be tagged for eviction to a lower level cache, which keeps the data available with a shorter latency than if the data had to be loaded from main memory again. This lowers the cost of prefetching useable data too far ahead and prevents cache trashing.

Abstract: Systems and methods are provided that facilitate memory storage in a multi-bank memory device. The system contains a memory controller and a memory array communicatively coupled to the memory controller. The memory controller sends commands to the memory array and the memory array updates or retrieves data contained therein based upon the command. If the memory controller detects a pattern of memory requests, the memory controller can issue a preemptive activation request to the memory array. Accordingly, memory access overhead is reduced.

The queue request order component is operable to track a queue request order. The request queue component is operable to queue and forward requests in accordance with direction from the queue request order component. In one embodiment, the storage component maintains a request without stalling a request in an aliasing condition.
