DRAM content in laptops will grow moderately by 25% this year

According to IHS iSuppli's DRAM research report, the growth of DRAM in PCs will slow down sharply in 2011 and the following four years, mainly due to the development of ultra-thin portable computers and cloud computing services. PC is a traditional big player using DRAM.

The DRAM content of each notebook is expected to be 4.0GB this year, which is lower than the previous optimistic expectations of 4.2GB. According to the new forecast, the notebook DRAM content in 2011 will only increase by 25% from 2010, an increase of 6 percentage points from the original forecast of 31%.

The gap between the initial expectations of laptop DRAM content and the adjusted expectations will become more apparent in the next four years.

The gap between the two is 0.2GB this year. In 2012, it will expand to 0.6GB. The DRAM content of each notebook will drop from 5.7GB to 5.1GB. This gap will increase to 1.0GB in 2013, expand to 1.9GB in 2014, and reach the peak of 2.4GB by 2015. As a result, compared with the original expectation, the 2012 growth rate will be estimated to decrease by 8 percentage points. 2013 The year will be reduced by 5 percentage points, by 8 percentage points in 2014 and by 1 percentage point in 2015. The DRAM content in the notebook is expected to be 10.2 GB by 2015, and the previous forecast is 12.6 GB.

Ultra-thin book and cloud: The main reason for the increase of DRAM content growth caused by DRAM content growth is the ultra thin book, which is produced by Intel's thin and light notebook, with a maximum DRAM capacity of 4GB and extra memory. The demand is met by NAND flash memory. Intel is expected to shift its focus from traditional notebooks to ultra-thin notebooks in order to compete more effectively with tablets such as the Apple iPad. The ultra-thin noteworthy attention will inhibit the growth of DRAM content, which will continue until at least 2014. After 2014, the ultra-thin market may begin to saturate.

With the expected growth of ultra-thin books, the DRAM market may benefit from one aspect. Since this new type of portable notebook may utilize higher-priced, lower-power high-end DRAM chips, the impact of slowing DRAM content growth may be mitigated, resulting in a reduction in overall losses. However, IHS believes that the ultra-thin book will still be a negative factor that the DRAM industry needs to deal with. It has the most serious impact on the DRAM industry.

The second factor that is expected to hinder the growth of laptop DRAM content is cloud computing. Although the concept of cloud computing has been proposed for many years, it is only now beginning to feel its impact on various types of equipment. A recent example is that the Amazon launch of the Silk browser shifts some of the complex tasks of the Amazon Kindle Fire tablet to the cloud. This is just one example of the increasing importance of cloud services. Cloud services will certainly have a long-term impact on the DRAM content of PC products.

The economic downturn and the rapid growth of tablet PCs are all detrimental to the DRAM industry. In addition to the above two major factors, there are many other factors that will inhibit the growth of notebook DRAM content in the short term. For example, because of the economic downturn, financially stressed consumers are less likely to let go and spend money, so the PC industry will introduce more inexpensive products and use fewer DRAMs to meet current needs. Although manufacturers will eventually increase DRAM content in PCs to compete with rapidly growing tablets in terms of technical parameters, in the short term vendors are more likely to include DRAMs in cost reduction targets in order to preserve valuable profits.

IHS believes that the period in which PC DRAMs grew at a rate of 40% in previous years has clearly become a thing of the past. DRAM makers know this and are now turning their attention to improving mobile DRAM production for smartphones and tablets, which may provide DRAM with the next growth opportunity. For example, the tablet's DRAM capacity will increase by nearly 120% this year, from 274MB last year to 598MB.

Mini USB

Antenk mini usb:The small USB socket found on digital cameras, external hard drives, USB hubs and other equipment. Mini USB is much smaller than USB Type A and B but twice as thick as Micro USB (see illustration below).

MINI USB, also known as Mini USB, is a USB interface standard. USB is the abbreviation of universal serial bus in English, which means "universal serial bus" in Chinese. It is a technology developed for data transmission between PC and digital devices. Standard USB, MINIUSB and microusb have become the most common USB interfaces. Compared with standard USB, MINIUSB is smaller and suitable for small electronic devices such as mobile devices.

Mini USB is divided into a type, B type and ab type. Minib type 5pin interface is the most common interface. Due to its excellent anti misplug performance and small size, it is gaining the favor of many manufacturers. This interface is widely used in card readers, MP3, digital cameras and mobile hard disks.

The ID foot is only used in OTG function. The Mini USB interface is divided into mini-a, B and ab interfaces. If your system is only used as a slave, then use the B interface. The system controller will judge the level of the ID pin and determine what kind of device is inserted. If it is Gaoping, it is the B connector. At this time, the system will do slave mode. If the ID is low, it will be a interface. Then the system will use HNP dialogue protocol to decide which is the master and which is the slave
OTG is the abbreviation of on the go, that is, OTG technology is to realize the data transmission between devices without host. It is mainly used in the connection between different devices or mobile devices for data exchange. For example, the digital camera is directly connected to the printer, and through OTG technology, the USB port between two devices is connected to print out the photos taken immediately; the data in the digital camera can also be sent to the mobile hard disk of USB interface through OTG, so there is no need to carry expensive memory card or carry a portable computer for field operation.

Except for pin 4, other interface functions of Mini USB are the same as those of standard USB. The fourth needle becomes the ID, which is connected to the fifth needle on the mini-a, and can be suspended in the mini-b or connected to the fifth needle.
