RAM Parts

KNOW YOUR PARTS RAM
Physically, this one PC components including components with small size and simple. Compared to other PC components.
At first glance, it is only in the form of a small piece of PCB, with several additional components of black. With additional points of contact points, to interact with the motherboard memory. This is in between.

1. PCB (Printed Circuit Board)
In general, green colored PCB board. On the PCB is some component of memory chips installed.
PCB itself is composed of several layers (layer). At each layer is attached path or circuit, to supply power and information. In theory, the more the number of layers used on the memory PCB, will increasingly cross-sectional area available in designing the route. This allows the distance between point and line width can be set more freely, and avoid noise interference antarjalur on the PCB. And overall will make the memory modules are more stable and faster performance. That is why in some ads for memory products, emphasized the number of layers on the PCB used memory module products.

2. Contact Point
Often also called the finger contacts, edge connectors, or leads. When the memory module is inserted into the memory slot on the motherboard, this is the part that connects between the motherboard information to and from memory modules. This connector is usually made of copper or gold. Gold has a better conductivity value. But the consequences, with a more expensive price. Better choice of memory module connectors adapted to the materials used on the motherboard memory slot. Two different metals, coupled with electrical current flow allows the PC to work more corrosive reaction.
At the contact point, which consists of hundreds of points, separated by a special indentation. Commonly referred to as a notch. Its main function, to prevent installation errors on the type of memory modules available DIMM slots on the motherboard. For example, DDR module has a notch is 73 mm from one end of the PCB (the front). While DDR2 has a notch at a distance of 71 mm from the tip of the PCB. For SDRAM, more easily distinguished, with the three notch on the contact point.
DRAM (Dynamic Random Access Memory)
The components shaped black boxes mounted on a PCB module is called DRAM memory. Called dynamic, because it only holds information in short periods of time and must be refreshed periodically. While the types and forms of DRAM or memory chip itself is quite diverse.
