Which cache mapping technique allows any block of main memory to be mapped to any block in the cache memory?
In Fully Associative Mapping, a memory block from the main memory can be placed into any available slot (line/block) within the cache. This provides the highest flexibility and lowest conflict rate (misses due to two blocks competing for the same spot), but it requires complex hardware for simultaneous searching across every slot, making it the most expensive and slowest mapping technique.
