- The quickest system memory is **cache [memory](https://answers.mindstick.com/qa/97327/what-is-memory-mapping-with-relation-to-microprocessor)**, which is required to keep up with the CPU as it fetches and executes instructions. Cache memory stores the data that the CPU uses most frequently. The register file, which comprises many registers, is the quickest part of the CPU cache. The CPU stores instructions and data in registers, which are compact storage areas.
- Level 1 cache, which is placed on the CPU itself, is the next fastest type of cache memory. Finally, the CPU is connected to (but not within) the Level 2 cache. Cache memory is stored in static random-access memory (SRAM).
