Technology.am (Sept. 22, 2009) — Samsung Electronics announced that it has been ramping up production of its 1Gigabit (Gb) OneDRAMTM.
First introduced in 2008, the gain in operational efficiency using Samsung’s 60-nm class OneDRAM is especially beneficial in complex multimedia handset applications such as smartphones.
Samsung’s 1Gb OneDRAM has a 1.3GBps data transfer speed, 20 percent faster than its previous 512Mb version. The OneDRAM chip is also seven times faster than a traditional dual-port RAM-based platform.
The chip’s 166MHz speed enables seamless operation with the processors, for full Internet browsing and teleconferencing.
The smaller number of overall chips required in Samsung’s OneDRAM-based platform allows use of a printed circuit board only two-thirds the size of those used in conventional handsets.
Samsung also provides its OneDRAM with a processor, NAND flash or OneNANDTM in a package-on-package (PoP) solution that measures 1.5mm in height and reduces the area coverage of the print circuit board by 40 percent. This PoP solution brings a seven-fold increase in performance with a 30 percent decrease in power usage.
The OneDRAM’s internal interface, which complies with the JEDEC low-power, double-data-rate (LPDDR) memory standard, channels data between the processors through a shared data area in the OneDRAM chip, eliminating the need for DRAM and double-port RAM chips when transferring data.
