Samsung has shown off what it claims is the world’s most powerful chip for use in memory cards.
The 64 gigabit (Gb) chips could be used to make flash memory, commonly used in MP3 players, capable of holding the equivalent of 80 DVDs, the firm said.
The chips are built using circuits with a minimum feature size of just 30 billionths of a metre (nanometre).
Rival firm Toshiba has said it is also working with similar technology. Both firms will release products in 2009.
Flash memory is a so-called non-volatile computer memory, primarily used in memory cards, USB drives and MP3 players.
Non-volatile memory retains information even when there is no power to the device.
Samsung said there was currently “exploding demand” for flash memory as a storage medium in a range of applications.
The new chips are designed to be used in a specific type of memory known as NAND flash.
NAND Flash is a special form of Flash memory. Flash memory is a memory technology that keeps data even when the power supply is cut off; this is known as a non-volatile memory type. Flash memory can be read pretty fast, but writing to Flash memory is pretty slow compared to many other -volatile- memory technologies such as SRAM or DRAM. Flash also has a limited number of write-cycles; manufacturers typically specify something in the area of 10,000 writes for the lifetime of the part.
