fully associative cache
A cache where data from any address can be stored in any cache location. The
whole address must be used as the tag. All tags must be compared simultaneously
(associatively) with the requested address and if one matches then its
associated data is accessed. This requires an associative memory to hold the
tags which makes this form of cache more expensive. It does however solve the
problem of contention for cache locations (cache conflict) since a block need
only be flushed when the whole cache is full and then the block to flush can be
selected in a more efficient way.
