Samsung is using 0.12 micron technology instead of the older 0.15 micron technology. Chips made using the new technology are smaller, which improves read speed and can be produced at a lower cost, Samsung said.
The NAND-type flash memory is used in devices such as digital cameras, handheld computers and digital music players as well as in memory cards such as Smart Media, Compact Flash and secure digital cards. The chip is designed to have faster rewrite characteristics and higher storage volume.
Samsung, which is also working on 2Gbit flash memory, claims it is the first to mass produce 1Gbit flash memory using 0.12 micron technology.
Its rival Toshiba is using 0.13 micron technology to manufacture 1Gbit flash memory, while Sharp said last year it expects to release flash chips that can hold 16Gbits of data manufactured using 0.1 micron technology by 2006.
