Memory: MT42L128M64D4LD-3 IT

Memory is an important component in computing systems, offering high-speed storage of data and code for immediate or future use. MT42L128M64D4LD-3 IT is a type of DDR3 (Double Data Rate 3) synchronous dynamic random access memory (SDRAM) module used in desktops and servers. This section describes its application field and working principle.

Application Field

MT42L128M64D4LD-3 IT is a DRAM memory module compatible with DDR3 standards. It is typically used in desktops and servers to add extra RAM. It offers 15.6 GB/s of bandwidth and has 1024 Megabytes (MB), or 1 Gigabyte (GB), of capacity. This module operates at speeds of up to DDR3-1600 (PC3-12800). It features four memory banks on a 240-pin DIMM (dual in-line memory module) with a solarized gold-plated connector and an 8-bit prefetch buffer. The MT42L128M64D4LD-3 IT module is designed for high-performance operation and offers superior heat dissipation and signal integrity. This memory module is suitable for applications such as games, professional software, audio and video capture, digital signal processing, and intensive data processing and analysis.

Working Principle

The MT42L128M64D4LD-3 IT is a type of synchronous dynamic random access memory (SDRAM) that uses a four-bank architecture to store and retrieve data. This memory module includes four independent banks of SDRAM circuits, each bank consisting of 16 million 256-bit words. A basic DDR3 module operates between 800 and 1600MT/s with 8-bit wide data and a CAS latency of 6 to 12 cycles. The MT42L128M64D4LD-3 IT module operates at up to DDR3-1600 (PC3-12800) speeds and has a CAS latency of 6 cycles. It also features an 8-bit prefetch buffer and can access data from adjacent memory locations with fewer clock cycles. The MT42L128M64D4LD-3 IT also uses a differential data strobe (DQS) signal to improve signal integrity. DQS improves data reception by pairing the clock signal with a periodic data signal that helps to compensate for deviations in signal timings caused by environmental conditions such as temperature, voltage, and mechanical vibration. The result is a fast and reliable data transmission.

Conclusion

The MT42L128M64D4LD-3 IT is a type of DDR3 SDRAM memory module used in desktops and servers. It offers 15.6 GB/s of bandwidth and up to DDR3-1600 (PC3-12800) speeds, 1024 Megabytes of capacity, and four independent banks of SDRAM circuits. It features an 8-bit prefetch buffer and a differential data strobe (DQS) signal to improve signal integrity. This type of memory module is suitable for applications that require high-performance operation, such as games, audio/video capture, and intensive data processing and analysis.
