The 16-gigabit NAND flash memory chip, equivalent to 2 gigabytes of storage, doubles a chip Samsung introduced in September 2004.
Samsung's flash business is already getting a big boost from Apple's new flash memory-based iPod Nano music players which were announced last week and due in 2-gigabyte and 4-gigabyte versions. The Nano will replace Apple's hard drive-based iPod Mini line.
Apple is a major purchaser of Samsung flash memory. An Apple spokesman declined to comment on whether the company plans to use the chip in future iPods.
The development means more mobile devices can use flash memory instead of hard drives, which can fail if dropped suddenly or produce skips in music if used in high-motion activities such as running. Flash memory is also lighter and more energy-efficient.
By putting together 16 of the new NAND chips it is possible to create a 32-gigabyte product that can store 8,000 MP3 audio files or 20 DVD movies.
"You will be able to take your entire music and personal video libraries with you," said Hwang.
Samsung, the largest producer of NAND and DRAM memory chips, said it plans to begin mass-producing the new chips in the second half of 2006.
Flash memory, which can save data even when power is switched off, is most often used in electronic devices such as MP3 players, digital cameras and key chain drives.
DRAM chips, volative memory that loses data when power is switched off, are most widely used in personal computers.
