secondary cache

secondary cache

[‚sek·ən‚der·ē ′kash]
(computer science)
High-speed memory between the primary cache and main memory that supplies the processor with the most frequently requested data and instructions. Also known as level 2 cache.

secondary cache

(memory management)
(Or "second level cache", "level two cache", "L2 cache") A larger, slower cache between the primary cache and main memory. Whereas the primary cache is often on the same integrated circuit as the central processing unit (CPU), a secondary cache is usually external.
