Heterogeneous Memory Virtualization for Speed-Capacity Balancing

The patent introduces a memory virtualization layer that acts as an intermediary between the CPU and heterogeneous memory components. This layer includes a translation lookaside buffer (TLB) that automatically translates virtual addresses to physical addresses across different memory types (DRAM, SRAM, non-volatile memory, storage devices), shielding applications from the complexity of programming heterogeneous memory systems while enabling fast access to appropriate memory components.

The system dynamically changes memory mapping parameters based on usage patterns. The memory virtualization layer monitors access patterns and automatically adjusts the mapping between virtual addresses and physical memory locations, transitioning data between different memory types optimally without requiring application-level programming changes.

The patent implements a nested memory hierarchy where faster memory types (SRAM, DRAM) are nested within the virtual address space alongside slower but larger capacity memory types (non-volatile memory, storage devices). The memory virtualization layer manages this nested structure, allowing the system to provide both high-speed access for frequently used data and large capacity for less frequently accessed data, effectively combining the advantages of different memory types.

The system dynamically manages memory allocation across the heterogeneous memory components. The memory virtualization layer continuously monitors usage patterns and dynamically relocates data between memory types based on current access patterns, ensuring that hot data resides in faster memory while cold data is stored in larger capacity memory, optimizing both speed and capacity utilization.
