RAM (Random Access Memory) or RWM (Read Write Memory) is the memory in which a computer places data during processing. The characteristics of this memory are:
- its access speed, this speed is essential to quickly provide the data to the processor.
- its volatility, this volatility implies that the data are lost as soon as the computer stops being supplied with electricity.
There are several types of RAM:
SDRAM or Synchronous Dynamic Random Access Memory is a particular type of RAM that has had a long career since it was used from Pentium to Pentium 4. It replaced RAM EDO in the heart of our computers .
the SDRAM synchronizes with that of the motherboard. Reading the data in synchronization with the bus of the motherboard makes it possible to avoid certain waiting times, and in particular that due to synchronization with the motherboard. The waiting cycle is thus reduced. The SDRAM can thus operate with a rate of up to 200 MHz and reduce its access time to 5 ns. In a PC, it comes in barrel with 168 pins in 64 bits and two notches.
