Memory CG8404AA Application Field and Working Principle

Memory is an important part of a device’s hardware, providing a means of storing data and instructions. Memory is a critical component of any system, whether it is a device intended to control a vehicle’s accelerator, store the music on your iPod, or track shipments at a warehouse. Memory components come in many different shapes and sizes and contain different technologies, but all memory uses the same basic principles.

CG8404AA is one type of memory, which is produced by the world’s leading memory manufacturer, Samsung. CG8404AA utilises dense, small-sized packages and advanced memory stack technology to reduce power consumption and heat dissipation and boost reliability. It has earned Samsung a great reputation in the memory industry.

Application Field

CG8404AA is optimised for use in automotive, industrial, and consumer-electronic applications, such as automotive media players, rearview cameras, digital signage and intelligent buildings. It is also ideal for High Definition (HD) displays, GPS and telematics, among many others.

CG8404AA is the perfect replacement for large packages such as CG8406 or CG8408, and delivers the same performance with 40% less board footprints.

Working Principle

CG8404AA is a type of high-speed synchronous dynamic random-access memory (SDRAM) that operates on a synchronous interface; one which is “synchronized” to an external clock. It is essentially an increased speed version of conventional DRAM (Dynamic Random Access Memory). While conventional DRAM accesses and refreshes memory data via an address-control multiplexer, CG8404AA works in concert with the clock, allowing simultaneous read and write operations to take place simultaneously in a single clock cycle.

Due to its design, SDRAM can be arranged in a double data rate (DDR) configuration, which allows it to effectively double the amount of data which can be transferred per clock cycle. Its fast access time, at 45-50ns, is almost twice as fast as conventional DRAM. This improved speed is the reason why it is used in the vast majority of consumer electronics and consumer applications.

CG8404AA also supports a variety of operational frequencies, from 133MHz to 800MHz; enabling it to easily integrate with a wide range of applications and technologies. Additionally, its low-voltage power mode is designed to reduce power consumption, allowing for a smaller DPACK package.

Conclusion

The CG8404AA is an advanced SDRAM memory manufactured by Samsung and optimised for use in automotive, industrial, and consumer-electronic applications. It operates on a synchronous interface, allowing simultaneous read and write operations to take place in a single clock cycle. It’s fast access time, low-voltage power mode and support a variety of operational frequencies, from 133MHz to 800MHz makes the CG8404AA the perfect choice for a variety of advanced application requirements.
