JS48F4400P0TB00A

Memory

The JS48F4400P0TB00A is a dynamic random access memory (DRAM) chip specifically designed to deliver high-performance data access and improved system performance. It is a specialized integrated circuit (IC) created to store data in memory so that a processor can access it quickly and efficiently. It is widely used in high-end consumer electronics devices for applications such as digital cameras and HDTVs.

Application Field

The JS48F4400P0TB00A chip offers a variety of features, such as high-speed data transfer, full-speed burst read and write cycles, improved system performance and better signal integrity. The chip’s low-power operation helps to reduce power consumption while achieving fast speeds. These features make it ideal for use in consumer electronics products requiring fast access to data stored in memory.

The chip can store up to 4GB of data in its 3.2-inch die size, with a maximum clock frequency of 200MHz. It is capable of operating in temperatures ranging from 0°C to 70°C, making it suitable for a variety of conditions. Furthermore, it is compliant with the JEDEC multiple-bank DRAM standard, making it an ideal choice for high-performance memory applications.

Working Principle

The JS48F4400P0TB00A chip works by storing data in its memory cells, which are organized into “banks” of memory. It is a synchronous dynamic random access memory (SDRAM) chip, meaning that it synchronizes itself with the system’s clock to allow data to be transferred quickly between its memory cells. The chip features an eight-bit data bus interface and can transfer data at up to 200MHz.

The chip uses a two-bank page-mode architecture, allowing it to access two banks of memory at the same time. This feature reduces latency and increases system performance. The chip also features auto-precharge and self-refresh capabilities, allowing the chip to automatically clear memory after it has been accessed, and to refresh contents to ensure quality of data. Furthermore, the chip supports Error Correcting Code (ECC) and parity, as well as cyclic redundancy check (CRC) for additional data correctness.
