Integrated Silicon Solution Inc. (ISSI) has introduced the IS43DR16640A 1Gbit DDR2 SDRAM organized as 64Mx16 and packaged in an 84-ball BGA.

This new device is available with clock speeds up to 533MHz (DDR2-1066), providing a data transfer rate of 4 gigabytes/sec in 32 bit systems. In addition to this new 1Gb device, ISSI also offers 512Mb and 256Mb DDR2 devices, with all three densities available in commercial, industrial and automotive grades. The 256Mbit density includes 8Mx32 and 16Mx16 organizations and for the 512Mbit density 32Mx16 and 64Mx8 organizations are available. In the second quarter, ISSI will add x8 versions of the 256Mbit, and 1Gbit devices. The DDR2 DRAM product family operates from a single supply voltage of 1.8V.

"We continue to expand our DRAM product line to include a variety of interfaces, densities, organizations, and temperature ranges targeted for automotive, networking, telecom, and digital consumer applications. The introduction of the 1 Gigabit density to our family of DDR2 SDRAM is an example of ISSI's long-term commitment to support a complete range of high-quality DRAMs using leading-edge technology," said Ron Kalakuntla, ISSI VP of marketing, ISSI. Key applications in networking and telecom include access nodes, aggregation nodes, VoIP, switches, routers, and packet optical transport. Automotive applications are infotainment and telematics. Other applications include network storage, STBs, DVRs and others.

In addition to SDR, mobile SDR/DDR, DDR, and DDR2 SDRAMs, ISSI also offers a complete line of both asynchronous and synchronous SRAM with densities from 64Kbit to 72Mbit. ISSI also has a range of Known Good Die memories in its portfolio.

Samples of the IS43DR16640A in both commercial and industrial temperature ranges are available now with volume production shipments beginning in Q2 10.
