SEOUL, Korea -- Troubled Hynix Semiconductor Inc. said Tuesday (July 29, 2003) that it has developed a 500-MHz 256-Mbit double data rate synchronous DRAM and that volume production would begin in August 2003.
The device is intended to as a main memory DRAM for personal computers, the company said.
Although Hynix describes the memory as a DDR500 part running at 500-MHz, the principle of the DDR is that data is transferred from memory on each of two phases of a single clock cycle. So a DDR500 device operates at a 250-MHz clock frequency but can transfer data 500 million times a second.
The DDR500 memory is available in FBGA, TSOP or QFP packages and is aimed at people who like to play games on PCs and therefore want higher clock frequencies and system performance.
Hynix said that for a time it expected the DDR500 to command a 10 percent 20 percent premium relative to DDR400 due to limited supply.
However, the export of Hynix DRAMs to the U.S are subject to tariffs in excess of 40 percent set to offset the effect of allegedly illegal subsidies from the South Korean government related to the conversion of massive debts built up ay Hynix into equity. The European Union has also set a similar tariff.
