It is known as Memory Cache to the component of hardware or software that stores data from previous searches for when they are requested in the future can access more quickly, this memory also known as auxiliary memory is volatile and fast access as RAM Memory although a little faster, and in turn is responsible for saving the recent data of the processor.

The cache memory is a special memory buffer that computers have, it is said to work in the same way as RAM, although it is smaller and faster. The cache is physically located in the middle of the processor and the RAM memory, in order to accelerate the exchange of data. The cache memory keeps temporarily and easily accessible those data that are required by the system to perform certain functions.

The word Cache comes from the French that means hidden or hidden. In a summarized way, the Cache Memory is a fast and volatile access memory like the RAM Memory, it is a temporary storage device of recent data so that in a search can enter faster and a special memory buffer that has any of our computers. Thanks to this small but effective hardware or software you can have a more organized, streamlined and simple access to certain data, saving time.

This Memory is considered by many as a powerful tool that makes possible a better performance, its location makes Processor and RAM Memory operate in a more agile manner and with a perfect performance.


There are different types of cache memory, which have the same purpose, although they vary according to their technological development.

Level 1 cache (L1): also known as internal memory, is integrated in the processor works at the same speed, is used to access important data and is often used. This cache is divided into two parts, one is responsible for storing the instructions and the other for the data.

Level 2 cache (L2): also known as secondary cache which is responsible for storing data and files recently, its structure is to reduce the response time and its speed is lower than the level 1 cache.

Level 3 cache (L3): This memory is located on the motherboard, speeds up access to data and instructions that were not located in the previous levels, in most cases it is used to feed the memory level (L2) and its speed is greater than the Level 1 Memory (L1) although its speed is lower than the Level 3 Memory (L3).
