AS4C4M16D1A-5TAN is a synchronous dynamic random access memory (SDRAM) device which incorporates integral power down circuitry that reduces power consumption by over 50 percent compared to most conventional SDRAM devices. The device is an industry-standard DDR2 memory module that can be used in virtually any motherboard or computing device that requires additional memory. This article will discuss the application fields and working principles of the AS4C4M16D1A-5TAN memory device.

Application Fields

The AS4C4M16D1A-5TAN is primarily used for PCs, laptops, digital video recorders and high-end gaming systems. It can also be used in digital devices such as routers, switches and modems. Additionally, it is suitable for secure digital card applications and devices that require large amounts of data storage. The device is also commonly used in cloud computing and virtualization applications, which require constant access to large amounts of memory.

Working Principle

The AS4C4M16D1A-5TAN device is a type of double data rate 2 (DDR2) SDRAM. Like all DDR memory devices, the device works by transferring data on both rising and falling clock edges, allowing for twice the number of transfers per clock cycle as compared to single data rate memory devices. The device has an 8-bit data bus and can run at speeds of up to 667 mega transfers per second (MT/s). Additionally, the device has a 5- nanosecond (ns) access time and can support CAS latency of up to 4 cycles.

The device also supports bursting with on-chip address pipelining and auto-precharge for enhanced system performance. Additionally, the device supports ECC (Error-Correcting Code) to detect and correct single bit errors. Such error detection and correction capability make the device ideal for high-reliability applications, such as servers and military equipment.

Additionally, the device features a low-power standby mode that can reduce the device\'s power consumption by up to 50 percent. This power-saving feature is enabled through the on-chip power down circuitry, which keeps the device in a low-power state when it is not active. This feature makes the device suitable for mobile applications, such as notebooks and other battery-powered devices.

Conclusion

The AS4C4M16D1A-5TAN is a high-performance, low-power SDRAM device that is suitable for a wide range of applications, including PCs, laptops, digital video recorders, gaming systems, secure digital card applications and virtualization applications. The device supports ECC for single bit error detection and correction, as well as on-chip address pipelining and auto-precharge for optimized system performance. Additionally, the device features a low-power standby mode that can reduce the device\'s power consumption by up to 50 percent. This makes the device suitable for battery-powered applications.
