[New 4Gb OneNAND(tm) Flash memory from Samsung reduces power consumption by half and a data read speed four times faster than conventional NAND Flash memory.]
Seoul -- Samsung Electronics Co., Ltd. announced that it has developed a 4Gigabit OneNAND(tm) Flash memory device for multimedia phones, featuring micro-compact dimensions, low power consumption and high performance in addition to its high density.
OneNAND is expected to be especially popular as the memory device powering tiny 3G mobile phones, advanced PDAs, a new generation of portable gaming systems and the highest performing digital cameras. The new OneNAND memory device operates on 1.8V, reducing power consumption to nearly half of the existing 3.3V level for other types of mobile memory. It also features a micro-compact size (1 1 x13x1. 4 mm), considerably smaller than mobile memory of the same capacity.
The 4Gb OneNAND boasts a sustained data read speed of 108 MByte/s, four times faster than conventional NAND Flash memory, and a write speed of 10 MByte/s, more than 60 times faster than NOR flash memory . It can store 250 more sequential photographs from a 5-megapixel camera phone, or up to 120 music files.
The 4Gb OneNAND memory is a quad die package (QDP) developed by stacking four 1Gbit OneNAND memory chips in a 90 nanometer production process developed last November.
