Elpida makes 4-Gigabit DDR3 SDRAM using 25nm process

Elpida Memory Inc has developed the new 4-gigabit DDR3 SDRAM made using 25-nanometer (nm) process. The new chip is the industry's first smallest 4-gigabit DRAM, claims Elpida.

Elpida says its 4-gigabit DRAM enhances productivity by about 45%, reduces operating current by about 25-30% and standby current by about 30-50% when compared with Elpida's 30nm 4-gigabit DDR3 SDRAM and also realized the highest speed data transfer rate.

The new 25nm DDR3 SDRAM is expected to find applications in PCs and in servers used in data centers and other facilities that perform large-scale information processing tasks. Other applications are likely to include tablet PCs and UltraBook (an ultra-thin notebook PC).

Key features of the new 25nm DDR3 SDRAM include:Part numbers EDJ4104BCBG / EDJ4108BCBG
Manufacturing process 25nm CMOS
Memory density 4-gigabit
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


Availability: Sample shipment and mass production of the new 25nm 4-gigabit DDR3 SDRAM is expected to start by the end of this year.
