Are you familiar with the term snooping?..

Answer / kanak

Let's take an example of different processors(along with
their independent caches) sharing the same memory system.

Now if this memory is a Read-Write memory and let's say
that one of the processors writes to this memory after some
data computation, all the processors need to update their
individual cache copies of the now modified memory. To do
this the concept of snooping is implemented. cache snooping
is the means by which each cache constantly
monitors/detects the bus for any write to a memory location
and if a write is found, it invalidates it current copy of
cached memory data and copies the new content over.
