CYD18S72V-133BBI Application Field and Working Principle
The CYD18S72V-133BBI (“CYD18S72V” in short) is a type of Dual In-line Memory Module (DIMM). It is mainly used for servers and high-end desktops to meet their memory requirements. It has a capacity of 72GB and a voltage of 1.35V.

The working principle of DIMM is based on the semiconductor process. A DIMM comprises several identical chips with a semiconductor substrate consists of transistors connected by metal wires to form integrated circuits (ICs). When activated, the transistors repeatedly store and release data as impulses of electricity, which makes up the instructions and data of the system. The metal wires are called traces and are connected to the package contacts at the edge of the module.

When installed into a PC, the DIMM device connects to the system’s memory controller. This controller provides the power and data transfer between the CPU and the memory. In the case of the CYD18S72V-133BBI, the memory controller is dual in-line which offers a higher data transfer rate at a lower voltage than single in-line modules. It also supports the Cyclic Redundancy Check (CRC) and ECC (Error Correction Code) capabilities, which provide extra protection against data loss by detecting and correcting any memory transference errors due to hardware or software problems.

The CYD18S72V-133BBI is designed to work under normal conditions in a temperature range of 0 to 85 °C (32 to 185 °F). It also has an operational voltage range of 1.35-1.75 V and is supported by 5-bit refresh functions. Furthermore, the DIMM offers fast data transfer rates of 1333MT/s and an SPD (Serial Presence Device) protocol to ease the installation and configuration process. This makes it the perfect choice for high-end users who require a reliable and high performance memory module.

The CYD18S72V-133BBI memory module can also be used for applications requiring multiple users, such as gaming, as it can rapidly store and access large data sets. It is also suitable for other applications related to scientific and complex computing. Additionally, its support for the latest memory technologies ensures maximum performance and enhanced system stability. Finally, the module is user friendly and offers flexible configuration options that allow users to customise the module’s settings to meet their individual requirements.
