Cacheminnet
Cacheminnet, often referred to in English as cache memory, is a small, high-speed storage layer between a computer's central processing unit and its main memory. It stores copies of recently accessed data and instructions to reduce average memory access time. Cache memory exploits temporal and spatial locality: recently used items and nearby data are likely to be used again soon.
Most modern CPUs implement a multi-level cache hierarchy, commonly with L1 as smallest and fastest, followed
For multiple cores, cache coherence protocols such as MESI ensure that data stored in private caches remains
Cache memory may also appear in other contexts, such as GPU caches, disk or OS page caches,
