ISSI unveils new 512Mb DDR2 SDRAM device

Claims to provide data transfer rate of 3GB/s in 32 bit systems

By CBR Staff Writer

Integrated Silicon Solution (ISSI) has expanded its family of DDR2 SDRAM products with the addition of 512Mb density. The IS43DR16320B (512Mb) device is organised as 32Mx16 and is available in an 84 ball BGA package.

ISSI said that the new device is available with clock speeds up to 400MHz (DDR2-800), providing a data transfer rate of 3 gigabytes/sec in 32 bit systems.

In addition to the 512Mb device, ISSI offers 256Mb DDR2 devices, with both densities available in commercial, industrial and automotive grades. The 256Mb density devices include 8Mx32 and 16Mx16 organisations.

The company said that it will add 1Gb devices organised as 64Mx16 and 128Mx8 as well as x8 versions of the 256Mb and 512Mb devices in the first quarter of 2009. The DDR2 DRAM product family operates from a single supply voltage of 1.8V.

Ron Kalakuntla, vice president of marketing at ISSI, said: DDR2 SDRAMs are being introduced in order to support the needs of our strategic customer base. Expanding our DDR2 SDRAM product offering is part of ISSI’s long-term commitment to support a complete range of high-quality DRAMs using leading-edge technology.

“We will continue to invest in our DRAM product line to include a variety of interfaces, densities, organisations, and temperature ranges targeted for automotive, networking, telecom, and digital consumer applications.

In addition to SDR, mobile SDR/DDR, DDR and DDR2 SDRAMs, ISSI also offers a line of both asynchronous and synchronous SRAM with densities from 64Kb to 72Mb.
