Cache memory<\/strong> is a very fast type of memory that allows specific functions to be performed to improve the overall performance of machines such as computers, smartphones and tablets.<\/p>\n\n\n\n

Unlike other memories, cache memory does not store information: its role is to store the information most frequently used by software and applications when they are active. This direct access determines the performance of a program, because it saves incessant exchanges between the processor and the random access memory (RAM).<\/p>\n\n\n\n

The cache memory is organized in three levels, with increasing storage capacity: level 1 cache (L1), level 2 cache (L2), and level 3 cache (L3)<\/strong>.<\/p>\n\n\n\n

Level<\/strong><\/th>Properties<\/strong><\/th><\/tr><\/thead>
L1<\/td>The level 1 (L1) cache is built into the processor (CPU). It is very fast, but its storage capacity is small.<\/td><\/tr>
L2<\/td>The level 2 cache memory (L2) has a larger storage capacity than L1. It can be integrated either in the processor or on the motherboard <\/strong>with a high speed link by computer bus <\/strong>to the central processor.<\/td><\/tr>
L3<\/td>The level 3 (L3) cache is slower than the previous ones. However, it has a higher storage capacity. In general, it is used to improve the performance of L1 and L2, especially in processors with a multi-core architecture. Each core <\/strong>has its own L1 and L2 cache, while the L3 is pooled.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
