Dynamic random-access memory (DRAM) is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit. The capacitor can be either charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1. Since capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically. Because of this refresh requirement, it is a dynamic memory as opposed to SRAM and other static memory.

The main memory (the "RAM") in personal computers is Dynamic RAM (DRAM). It is the RAM in laptop, notebook and workstation computers as well as some of the RAM of home game consoles (PlayStation3, Xbox 360 and Wii).

Quelles sont les extensions de la RAM possibles possibles pour ce notebook (actuellement 8 Go)?

Merci d'avance !
