Elpida sampling 2Gb DDR3 SDRAM made using 25nm process

Elpida Memory, Inc. has sampled shipments of the smallest chip available in the DRAM semiconductor memory industry, which uses ultra fine-width process migration technology to achieve a circuit line width of 25 nanometers (nm).

Elpida says the new 25nm process-generation product being shipped is DDR3 SDRAM with a memory capacity of 2-gigabits, used for PC and server applications and the process will be used to develop applications of Elpida's Mobile RAM for use in various kinds of mobile devices, starting with the growth areas of smart phones and tablet PCs.

Key Features of the25nm DDR3 SDRAM include:
Data width x4-bit / x8-bit
Per pin data transfer rate 1866Mbps and higher
Supply Voltage (VDD) 1.5V, 1.35V (Low voltage)
Operating case temperature range (TC) 0 to 95°C

Special features of the 25nm SDRAM include lower current usage (roughly 15% less during operation, 20% less when on standby) compared with Elpida's current advanced process 30nm-generation products and one of the highest data transfer rates in the industry, as explained by Elpida.

The new 25nm DDR3 SDRAM's other applications include mobile phones, smart phones, tablet devices, ultra-thin notebook PCs, game consoles, flat screen TVs, set-top boxes and other kinds of digital consumer electronics.
