1-Gigabit XDR DRAM works at speed of 7.2 GHz

Elpida has released industry's first 1-Gigabit XDR DRAM based on a x32-bit configuration. This memory IC runs at very high speed of 7.2GHz, and is faster than GDDR5 type memory chip. This DRAM offers a data transfer rate of 28.8 GB per second. The targeted applications of this device are gaming consoles, HDTV and Blu-ray disc recorders.

XDR DRAM is produced at 65nm process technology. It works at 1.5 Volts and support an x32-bit interface. It provides a one-chip solution that, compared with two x16-bit configuration 512 Megabit XDR DRAMs, consumes 35-40% less power and requires less space.

Key Specifications:

Interface: DRSL (DQ pin), RSL (RQ pin)
XDR Technology: Octal Data Rate, DRSL, Flex Phase
Operating Temperature Range: 0 to 100°C
Package: 104-ball FBGA (x4/x8/x16)
