Random Access Memory (RAM) is a computer data storage device. RAM perform important functions in a computer. All the important data needed processors, stored in RAM, allowing the processing of data quickly and efficiently in a random order. In general, the speed of transfer is in accordance with the speed of the processor. In contrast, other data storage media such as hard disk read and write data only in a predetermined sequence (in a row). This is due to the limitations of mechanical design. Therefore, the time to access the data given location varies depending on the physical location.
Basically, RAM is determined by the quality of integrated circuits. The better the quality of the materials, the better the integrated circuits in storing data. Actually, modern types of DRAM are now not accessed randomly. However, many types of SRAM are still accessed randomly. RAM is often associated with volatile types of memory, where information is stored will be lost if power is removed.
Some manufacturers use a variety of different quality silicone materials in the manufacturing process. Most manufacturers use medium quality silicon, and very rarely use the high-quality.
The selection of high-quality integrated circuits may affect the performance of the memory in the computer system. The better the quality of the integrated circuit, the faster the data transfer. On the other hand, the data storage problems can emerge from low-quality integrated circuits, so the processor does not get the required data, then disrupt the computer system as a whole. This is why computers tend to crash.
Therefore, there are some things you might need to consider before replacing or buying new RAM.
