Samsung has begun sample production of its fastest DDR (double data rate) SDRAM (synchronous dynamic random access memory) chip to date.
The new chip can operate at speeds of up to 300MHz and has a capacity of 128Mb (megabits). Available in a 4x32Mb configuration, the chip has a data transfer speed of 600Mbps (megabits per second) and total operating speed of 2.4Gbps (gigabits per second), said Samsung.
The company announced the development of the 300MHz DDR chip in May this year. At the time Samsung said the processor would have a capacity of 64Mb when it reached mass production, which is still scheduled for the third quarter of this year.
DDR memory can transfer data at twice the speed of conventional SDRAM chips and is currently fighting with a proprietary memory interface technology developed by Rambus, called RDRAM (Rambus dynamic RAM), for dominance in the computer memory market.
Because high data transfer speeds are the key feature of both technologies, each is being targeted at the high-performance graphics and video markets in addition to high-end personal computers and workstations.
Samsung said it held a 50 percent share of the world DDR SDRAM market in the first quarter of this year.
