Abstract
En los últimos años, la llegada de las nuevas tecnologías y la digitalización ha llevado asociada un aumento exponencial de la cantidad de datos generados. Desde un punto de vista tecnológico esto plantea nuevos retos que abordar. Un aumento exponencial de la cantidad de datos no puede suponer un aumento también exponencial del espacio en el que almacenarlos. Es evidente que se necesitan sistemas con una densidad mayor de almacenamiento de información. A su vez, el aumento de los datos almacenados lleva ligado un aumento del tiempo de acceso por lo que es necesario aumentar también la velocidad de acceso. Pero además, mantener la información guardada y trabajar con ella está empezando a suponer un problema serio de consumo de energía que es necesario afrontar...
In the last years the emergence of new technologies and the digitalization has led to an exponential increase in the amount of data generated worldwide. From a technological point of view, this situation presents new challenges that need to be addressed. Keeping the same technology, an exponential increase in the amount of data means an exponential increase in the space used to store this information. However, this is not affordable. It is clear then that new memories with a higher storage capacity are needed. Even more, the increase of data would lead to an increase in access time, which makes mandatory the development of new systems with faster read/write data access. Finally having real time access data implies an increment of the amount of energy which, in mid and long term, suppose a serious problem of energy consumption, linked to global warming...
