IS42S16800D-75ETL-TR Memory Application Field and Working Principle

IS42S16800D-75ETL-TR is a kind of Double Data Rate Synchronous Dynamic Random Access Memory, better known as DDR SDRAM. It is a type of integrated circuit which allows user to gain storage access to digital information within a computer. The DRAM used in the IS42S16800D-75ETL-TR is capable of sending and receiving data at a much higher frequency rate than other types of random access memory. As such, it is a cost-efficient solution for those who need a great amount of reliable, high-speed memory.

Applications

The IS42S16800D-75ETL-TR is used in many different applications. It is primarily used in data storage systems such as servers, RAID drives, and storage controllers. Additionally, it is used in embedded systems, high-performance graphics cards, and gaming consoles. It is also used in industrial controls, medical systems, set-top boxes, and a myriad of other applications.

Technical Specifications

The IS42S16800D-75ETL-TR is a DDR2 SDRAM using 72-bit data lines. It has an access time of 7.5 nanoseconds and a cycle time of 15 nanoseconds. It has a maximum operating frequency of 800 MHz and a peak data transfer rate of 6.4 Gb/s. The module includes 32 chip select pins, one channel address pin, 8 channel input pins, and 4 data mask pins. It has a data bus that is 72 bits wide and can store up to 1536 Megabits of data.

Working Principle

The IS42S16800D-75ETL-TR is a type of DDR memory, which stands for Double Data Rate. This means that data is sent and received on both the rising and falling edges of a clock signal. This significantly increases the speed of data transmission, allowing for faster access times and higher data transfer rates.When data stored in the memory is read, it is first sent to the output buffer, which prepares it for transmission. The data is then placed on the data bus and is then sent to the requestor using special control signals. When new data needs to be stored in the memory, the requestor sends it on the data bus, which is then stored in the memory.

Conclusion

The IS42S16800D-75ETL-TR is a DDR2 SDRAM that is used for a variety of applications requiring high-speed, reliable memory. It has a maximum operating frequency of 800 MHz and a peak data transfer rate of 6.4 Gb/s. The workings of the memory are based on the Double Data Rate principle, which allows for quicker access to and transmission of data.
