What is a memory cache-fully-associative?

A memory cache that is fully associative means that any block of data can be stored in any cache location. In other words, each block of data in the main memory can be placed in any cache location, without any restrictions. This allows for more flexibility in caching and reduces the chances of cache conflicts. However, it also requires more complex hardware and increases the cost of the cache system.
