LG Semicon develops new DRAM

LG continues to deploy Rambus, an advanced technology that speeds the performance of memory chips, this time in a 64-megabit version.

South Korean chipmaker LG Semicon continues to deploy advanced technology that speeds the performance of memory chips, this time announcing it has developed a 64-megabit version of a Rambus DRAM chip.

LG claims to be the first company to adopt the Rambus interface--a licensed technology which speeds the flow of data between microprocessors and memory chips--to 64-megabit DRAMs (dynamic random access memory). The chip is likely to be utilized in machines running demanding 3D graphics applications.

Earlier this month, LG said it had started commercial production of an 18-megabit Rambus DRAM, also intended for graphics applications. DRAM chips are typically produced in 16-megabit versions, but a number of manufacturers are shifting to higher-capacity 64-megabit DRAMs.

Rambus memory technology addresses a data flow problem inherent in computers: Because the processor operates much faster than standard memory can deliver the required data, bottlenecks occur. Rambus is designed to move data to the processor more quickly by doubling the width of the memory bus, the pathway between memory and the processor.

Rambus is especially popular for use as a graphics memory because it can process multimedia data in real time. A number of leading memory manufacturers, including Intel, Samsung, and Mitsubishi, have already licensed the Rambus technology and said they will use it for this purpose.

An LG statement said the new 64-megabit memory chip has a data transmission speed of 700MB per second, four times faster than the comparable high-speed synchronous DRAM.

A unit of South Korea's LG Group, LG said it plans to begin mass producing the chip from early next year.
