Low Power DDR SDRAM

Low Power DDR SDRAM means Double Data Rate Synchronous DRAM.

Unlike SDR (Single Data Rate), which can only read or write once within a single clock cycle, the double data transfer rate of DDR refers to the ability to read or write twice within a single clock cycle, resulting in double the efficiency.

What is Low Power DDR SDRAM?

Low Power DDR SDRAM (Low Power Double-Data-Rate Synchronous- DRAM) is a type of DRAM that can read or write twice within a single clock cycle. It brings the double efficiency result.

The operation of Low Power DDR SDRAM is similar to standard DDR SDRAM. It reads data on both the rising and falling edges of each clock cycle, which makes DDR memory modules twice as fast in data transfer rate as SDR.

In addition, Low Power DDR SDRAM also has other capabilities of power saving.

What are the benefits of Winbond Low Power DDR SDRAM?

Here are the following key features:

Wide range Densities and flexible Configuration:

Winbond offers a wide range of densities and flexible chip configurations, it’s suitable for various mobile applications.

 

Low voltage settings:

Winbond provides low power IC to operate efficiently in lower voltages. It’s optimal solutions for IoT devices.

 

Partial-Array Self-Refresh Mode (PASR):

Winbond Low Power DDR SDRAM integrates a crucial power-saving mechanism in the form of the Partial-Array Self-Refresh (PASR) sequence. With PASR technology, the memory can be refreshed on a per-bank basis, rather than whole fresh. In this mode, the memory can preserves critical data only to reduce the overall power consumption. This ensures only data necessary to an active computing process is refreshed.

Deep Power State:

To improves battery life for mobile devices, deep power down state allows low-power DDR to enter an ultra-low power state if the data retention is not a priority.

What applications are suitable for Low Power DDR SDRAM?

Low Power DDR SDRAM is a high-performance, low-power memory technology that is suitable for use in handheld devices and mobile devices that require long-term operation and battery life. It is suitable for use in the following application:

 

Handheld, Smartphones, and tablets:

These devices require long-term operation, and Low Power DDR SDRAM can provide longer battery life while achieving high-speed data transmission and processing.

 

Camcorders and Surveillance:

It can support for high-speed image and video processing, which is required for photography and videography.

 

Automotive and embedded systems:

Low Power DDR SDRAM can handle high-speed data processing and storage applications in automotive systems, such as autonomous driving, intelligent safety systems, and entertainment systems.

 

IoT devices:

In recent years, the IoT applications have a significant transformation. Rather than simply analyzing data from endpoint sensors or edge devices, it has evolved to provide real-time interfaces. This new paradigm, referred to as AIoT, has the potential to significantly reduce system response times and overall power consumption. Related products have already appeared in a variety of contexts, including smart speakers, smart doorbells, and smart manufacturing. Low Power DDR SDRAM has also emerged as a pivotal technology in the AIoT ecosystem. Its small form factor, high bandwidth, and low power consumption make it a perfect fit for AIoT computing.
