Cache Algorithms for Memory Management

Cache Algorithms for Memory Management

The LRU (Least Recently Used) procedure is a displacement strategy for managing buffer memories and caches. Unlike FIFO (First In First Out), where the oldest entry is displaced, the LRU method overwrites the entries from the page that has not been accessed for the longest time. Other cache algorithms are Least Frequently Used (LFU), Not Recently Used (NRU) and Most Recently Used (MRU).
