second level cache (L2)

The Level 2 cache (L2) is an external processor memory that is housed on a separate chip.

However, the trend is increasingly to integrate the second level cache, just like the level 1 cache, into the microprocessor architecture, which has led to the renaming of the external cache as level 3 c ache.

Embedding the caches

L2 caches cache the data from main memories and thus make it available to the processor more quickly. They can be operated at full or half clock frequency. Level 2 caches have storage capacities of a few megabytes( MB). Some central processing units( CPU), such as Intel's Core 2 Quad, have a Level 2 cache with a memory capacity of over 10 MB.
