ISSI announces 1 Gb high speed DDR2 SDRAM

SAN JOSE, USA: Integrated Silicon Solution Inc., a leader in advanced memory solutions, has added the 1 Gigabit density to its family of DDR2 SDRAMs.

The first device at this new density is the IS43DR16640A which is organized as 64Mx16 and packaged in an 84-ball BGA. This on-going expansion of the DDR2 SDRAM product family adds to ISSI's already extensive offering of DRAMs.

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 256Mb density includes 8Mx32 and 16Mx16 organizations and for the 512Mb density 32Mx16 and 64Mx8 organizations are available. In the second quarter, ISSI will add x8 versions of the 256Mb, and 1Gb devices. The DDR2 DRAM product family operates from a single supply voltage of 1.8V.

Ron Kalakuntla, ISSI Vice President of Marketing, said: "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."

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, set-top boxes, 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 64Kb to 72Mb. ISSI also has a range of Known Good Die (KGD) 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, 2010.
