Abstract
In general, a system and method is provided for dynamically reallocating computer memory. A mapper receives requests to access data. The requests include bus addresses, and the mapper maps the bus addresses to memory unit addresses based on a plurality of mappings maintained by the mapper. The memory unit addresses identify a plurality of memory locations including a destination memory location and a source memory location. Data requested by the requests received by the mapper is accessed based on the memory unit addresses mapped from the bus addresses included in the requests. When desired, a data value from the source memory location is dynamically moved to the destination memory location, and the mappings are updated such that a bus address mapped to a memory unit address identifying the source memory location is instead mapped to a memory unit address identifying the destination memory location.
