L3 cache

(Level 3 cache) A memory bank built onto the motherboard or within the CPU module. The L3 cache feeds the L2 cache, and its memory is typically slower than the L2 memory, but faster than main memory. The L3 cache feeds the L2 cache, which feeds the L1 cache, which feeds the processor. See L1 cache, L2 cache and cache.
