second-level cache

Definitions

Electronics

  • A memory cache which utilizes a memory bank between the CPU and main memory. This contrasts with first-level cache, which is built right into the CPU. First-level cache is faster, but smaller than second-level cache, while second-level cache is still faster than the main memory. Also called secondary cache, level 2 cache, or external cache.
