L2 cache

(Level 2 cache) A memory bank built into the CPU chip, packaged within the same module or built on the motherboard. The L2 cache feeds the L1 cache, which feeds the processor. L2 memory is slower than L1 memory. See cache.


L2 Cache Locations
Modern CPU chips have a built-in L2 cache; however, L2 caches have resided outside the CPU on earlier computers.
