IS42SM16160D-7BLI is one of the most important components in the memory sector. It is a cost-effective medium-density 16M-bit synchronous dynamic random access memory (SDRAM). The IS42SM16160D-7BLI are designed to meet the PC100/PC133 SDRAM specifications and can be used for applications in desktops, notebooks, and other embedded systems. In this article, we will first discuss the application field of the IS42SM16160D-7BLI, and then explore its working principle.

Application Field of IS42SM16160D-7BLI

The IS42SM16160D-7BLI is designed for PC100/PC133 applications and provides a cost-effective solution for system integrators. It is highly suitable for desktops, notebooks, and other embedded systems because of its low power consumption and high performance. The device has been tested and verified to reach the enterprise-level standard according to JEDEC. The IS42SM16160D-7BLI is also backward compatible with older DRAM devices, allowing systems to scale performance easily.

The device has a number of features that make it appealing to system integrators. The primary benefit of IS42SM16160D-7BLI is its speed. It has a maximum continuous read/write speed of 66 MHz, which offers a considerable performance boost over older DRAMs. Additionally, its low power consumption (1.8V) and small form factor (FBGA) make it suitable for embedded systems that require high performance without consuming excessive power.

Working Principle of IS42SM16160D-7BLI

The main operational principle of the IS42SM16160D-7BLI is based on the synchronous dynamic random access method (SDRAM). The device is composed of a memory array, address lines, data lines, a control logic unit, and a clock generator. The memory array is organized into memory banks and cells. Each cell stores one bit of data, and the banks are organized into rows and columns.When the memory device is activated, an address of the desired cell is sent to the address port. The address is then decoded, and the corresponding row and column are selected. The data stored in the cell is then read and sent to the data lines.

The control logic unit handles all commands sent to the device. These commands are initiated by software or the system bus. The logic unit then sends the corresponding control signals to the various components of the device. The clock generator sends timing signals to the various components, allowing them to synchronize the data transfers.

The IS42SM16160D-7BLI also has several built-in functions to ensure reliability. It provides advanced self-refresh and temperature-compensated self-refresh capabilities, which help it maintain the data stored in its cells. Additionally, the device supports programmable write protection, which allows data to be stored in the memory even when the power is turned off. These features make the device an ideal choice for memory-intensive applications.

Conclusion

In conclusion, the IS42SM16160D-7BLI is a high-performance, low-power SDRAM designed for PC100/PC133 applications. Its main operational principle is based on the synchronous dynamic random access method, and it has a number of built-in functions to ensure reliable operation. The device is suitable for desktop, notebook, and embedded applications, making it one of the most popular devices in the memory sector.
