Memory Module Reconfiguration for Shared System and Accelerator Use

The patent implements dynamic memory area allocation by enabling the memory controller to reconfigure memory regions between system memory and acceleration operation modes based on runtime demands. The memory area excluded from system memory map can be dynamically assigned to acceleration operations, and this allocation can be changed adaptively according to system needs, resolving the contradiction between fixed allocation reliability and flexible adaptability.

The patent creates a multi-functional memory architecture where a portion of the memory device can serve dual purposes: functioning as system memory when needed and being reassigned to acceleration operations when required. The memory controller manages this universal memory resource by excluding specific memory areas from the system memory map and allocating them to acceleration operations, allowing the same physical memory to fulfill multiple functional roles and eliminating the trade-off between acceleration performance and system memory capacity.
