South Korean chipmaker Hynix Semiconductor Inc. has developed a 2Gbyte DDR2 memory module with operating speeds of 800MHz, which makes it the fastest of its kind in the industry, the company said. Hynix said that it was able to produce the improved module for personal computers using advanced wafer-level packaging technology (WLP).

In WLP technology, the die and package are manufactured and tested on the wafer prior to singulation, making it different from all other package types. Accordingly, the area the package occupies when mounted onto a printed wire board or other substrate is the size of the die.

Hynix said its WLP technology enables it to reduce production costs by more than 20 percent. It added that the new module is highly stable in operation, and its heat emission, speed and power characteristics have been improved, making the module fit for devices requiring higher-speed data transfers.

Hynix claimed its DDR2 doesn't need the pins that are normally required for interconnection with other components, which decreases signal delays and increases the operating speed.

In addition, the memory module's components can be used in existing commercialized memory modules, since they meet the standards of the Jedec Solid State Technology Association, Hynix said.

Hynix's announcement about its new DDR2 comes a month after the company introduced a family of components and high-capacity modules based on the industry's first 60nm, 1Gbit DDR2 DRAM. Hynix has said the 1Gbyte DDR2 DRAM will go into mass production during the first half of this year.

The 2Gbyte DDR2 is based on 90nm process technology. The company did not say precisely when its memory module is scheduled for volume production.

"The WLP technology used for the new 2Gbyte memory module will also be applied to the 60nm 1Gbit DDR2 DRAM," a spokeswoman for Hynix said.

When it announced the development of its 60nm 1Gbit DDR2 DRAM chips last month, Hynix said it would continue to enhance the 60-nm process for use in future high-density DRAM components and such high-performance products as graphic and mobile DRAMs.

Hynix is the first DRAM supplier to be validated by Intel on the 1Gbit DDR2 DRAM component. Modules using this component are under evaluation, according to the company. also be applied to the 60nm 1Gbit DDR2 DRAM," a spokeswoman for Hynix said.
