Memory IS45S32200L-7BLA2 application field and working principle

The IS45S32200L-7BLA2, manufactured by IDT, is a high speed synchronous DRAM (SDRAM) with a 16Mb (2M x 8) capacity. This cost-effective memory solution is the most cost-efficient solution for computing systems, cell phones and small form factor applications, where space and low power consumption are critical. The IS45S32200L-7BLA2 SDRAM features low power consumption and high reliability, making it suitable for applications that require high performance memory.

The IS45S32200L-7BLA2 has a 4-bit asynchronous input/output bus interface, allowing for high speed data transfer. The device is optimized for the maximum operating clock frequency of 166MHz. This frequency gives the device the capability of transferring data at up to 6.4Gbps, allowing it to offer maximum performance while consuming less power.

The IS45S32200L-7BLA2 also offers an innovative self-refresh feature, which allows the device to maintain its contents without the need for external refresh signals. This feature increases the endurance of the device and reduces power consumption. Additionally, the device offers dynamic power down modes, which allow the device to enter low power states when not in active use.

In terms of its application fields, the IS45S32200L-7BLA2 can be used in a variety of computing systems, such as servers, network-attached storage systems, and desktop machines. It can also be used in cell phones and other portable devices, such as digital cameras, PDAs and MP3 players, as well as in embedded systems, such as set top boxes, routers and switches. This device also accommodates non-volatile memory requirements in automotive applications.

The Working Principle of IS45S32200L-7BLA2

The IS45S32200L-7BLA2 SDRAM follows the same basic principles of operation as other types of memory devices. The device stores information as electrical charges on capacitors. When a transistor is connected to a capacitor, it is said to be charged, creating a “1” bit. When the transistor is disconnected from the capacitor, it is said to be discharged, creating a “0” bit.

The IS45S32200L-7BLA2 SDRAM is operated by a clock signal, which determines the device’s speed and how fast it can access data. The clock signal is activated by a memory controller, which also controls the transfer of data between the main memory and the CPU. During a read operation, the memory controller will activate the clock signal, causing the capacitors to discharge, which signals the SDRAM to transfer a row address onto the output bus. The row address is then provided to the CPU, which can access the data stored in that row. During a write operation, the CPU will send a row address and data to be written onto the SDRAM’s input bus, where it is stored on the appropriate row of memory cells.

The IS45S32200L-7BLA2 SDRAM also makes use of a self-refresh feature, which allows the device to maintain its contents without the need for external refresh signals. This feature allows the device to remain in an idle state for longer periods of time, reducing power consumption and increasing reliability.

Conclusion

The IS45S32200L-7BLA2 is a cost-efficient memory solution that is optimized for high speed data transfer and low power consumption. It has a wide range of application fields and is suitable for a variety of embedded systems, as well as computing systems, cell phones, and other portable devices. The innovative self-refreshing feature of the device further underscores its usefulness and enhances its reliability.
