Computer architecture with unified cache and main memory and associated methods

A memory management method, comprising:

• providing a central processing unit;
• providing one or more than one cache memory proximal the central processing unit being operatively connected to the central processing unit;
• providing a main memory;
• wherein, at least one cache memory is unified with the main memory;
• and
• providing a plurality of sets of computer executable instructions stored in computer system, wherein at least one set of computer executable instructions contains instructions for the system to perform the following tasks in coordination with the hardware components in the system:
• CPU sends a data request and access the cache portion of the unified cache and memory system;
• conducting fully associative search on the unified cache and main memory system as one range of physical memory;
• if matching data is found on the cache portion, return the data to the CPU;
• if matching data is found on the main memory portion, swapping the matching data to the cache portion and then return the data to the CPU;
• if matching data is not found in either the cache portion or the main memory portion of the unified cache and main memory system, triggering the operating system to handle the page fault.
