>> Samsung Electronics Unveils 0.7Mm Super-Thin Flash Memory

By Shin, Hwa-su

eTimes (Korea)

Samsung Electronics' semiconductor business division (chaired by Lee Yun-u) announced on May 17 that it has developed the world's thinnest 0.7mm thick 512 Mb NAND type flash memory, which is soon to make its debut in the market.

The mobile information device-applicable flash memory is 40% as thin as existing models. The company used a pin type WSOP package technology, a step ahead from TSOP that generates 1.27mm-thin chips. In addition, it also adopted a super-thin film wafer processing technology and special plastic package material.

With the development, Samsung has improved the level of semiconductor package technology. And as the new product is compatible with existing flash memory chips without changing design structure, the company has boosted cost competitiveness only to take an advantageous position in the market.

Recently, demand for smaller-sized chips with enhanced speed and capacity has been increasing in the market. Therefore, chipmakers are waging fierce competition by adopting advanced package technologies that lower chip price by 10 to 15%.

The company plans to launch mass production of the product, which is to be used for IMT2000 mobile phone memory cards, in the middle of next month and to introduce a 1 Gb model next year. The chipmaker recorded 400 million dollar in flash memory sales last year and plans to achieve 640 million this year. <<

ZTE offers cdma2000 1x Voice Service

After replacing channel cards, ZXC10 CDMA system of ZTE offers cdma2000 1x telephony service, allowing communications among 3G and 2G mobile phones, among 3G mobile phones, and among 3G/2G mobile phones and fixed phones. This is the first CDMA system that offers cdma2000 voice in China.

Cdma2000 broad communication technology is one of the most important 3G mobile communication solutions. Cdma2000 1x, the first phase of cdma2000, supports up to 144-kbps package services, offering at least two times of capability of narrow CDMA (IS-95) system. Besides, it is compatible with the narrow CDMA.

Cdma2000 technology is promising globally. A large cdma2000 network is being built in Korea. The narrow CDMA technology was employed in north America, Korea, Hong Kong, Australia, and other countries and regions, which will be evolved to 3G one by using cdma2000 technology. China Unicom (www.chinaunicom.com) is licensed to set up a nationwide CDMA network which will be also evolved to 3G one by cdma2000 technology. Cdma2000 1x will be widely used all over the world.


The début of the broad CDMA system will increase ZTE’s competitive edges, allowing it to occupy more shares of market in mobile communication.

ZIF-NIF makes it easy to make GPRS handset for all
four frequencies, 900-1800-1900-2100Mhz!!

That is, not one line of code need to be rewritten
going from 1900 to 2100MHz, not even carrier
trackers due to slightly increased doppler effect..

snap

When will GPRS make it into the open? CDMA2000, etc, seems to work in the open.
