Abstract:
Systems, apparatuses, and methods for predictive memory access are described. Memory control circuitry instructs a memory array to read a data block from or write the data block to a location targeted by a memory access request, determines memory access information including a data value correlation parameter determined based on data bits used to indicate a raw data value in the data block and/or an inter-demand delay correlation parameter determined based on a demand time of the memory access request, predicts that read access to another location in the memory array will subsequently be demanded by another memory access request based on the data value correlation parameter and/or the inter-demand delay correlation parameter, and instructs the memory array to output another data block stored at the other location to a different memory level that provides faster data access speed before the other memory access request is received.
