12 Memory

How much memory is inside a micochip?

How much memory is contained inside a micro chip? Can it contain a full program or only a few routines?

If you're talking about a CPU, they don't contain any RAM memory. They can contain Level 2 cache memory, anywhere from 1 MB to 32 MB. Core2Duo processors commonly have 3, 6or 12 MB of cache. A standard desktop or laptop computer cannot run without standard RAM memory on the motherboard.

The on-die cache L2 memory is extremely fast, much faster than the RAM out on the motherboard.

The cache temporarily holds whatever the CPU is working on - data, program code, and some complex algorithms determine what is kept in cache and the order it is used and erased.
