SOUTH PORTLAND, Maine -- Fairchild Semiconductor International Corp. today claimed to be the first chip maker to offer a complete memory interface solution for dual data rate (DDR) memory modules that boost memory and operating speeds in PCs and servers for the Internet.
The solution is aimed at grabbing more business with memory module makers, which are beginning to build dual in-line memory modules (DIMMs) for DDR synchronous DRAMs. The new offering consists of three devices: the FMS7857 phase locked loop (PLL) clock driver; the SSTV16857 registered buffer, and the FM34W02 serial presence detect EEPROM.
All combined, these devices synchronize and control clock and data signals, allowing central processors to determine the capacity and electrical characteristics of memory chips in PCs and Internet servers. This technique provides more memory capacity at higher speeds, according to the company.
Fairchild estimates that the market for these devices will exceed $100 million in 2001 worldwide.
The South Portland company said it is only chip supplier to offer a complete support for DDR DIMMs, configured as 184-pin, 2.5-volt PC200/PC266 memory modules. These modules provide 72-bit wide registered DDR SDRAMs in systems.
These new products are part of Fairchild's push to gain market share in high-growth interface applications. The DDR memory module solution was jointly developed by Fairchild's new Interface and Logic Group with the company's Analog and Mixed-Signal Products Group. Fairchild formed the Interface and Logic Group earlier this year to focus on Internet hardware and system applications (see Feb. 4 story).
The new solution is comprised of the FMS72509 and FMS72510 PLL clock drivers; the 74VCXF162835, 74VCX162838, and 74VCX162839 registered buffers; and the FM34W02 serial presence detect EEPROM. This package is intended for use in 168-pin, 3.3-volt, 133-MHz registered SDRAM DIMMs.
The FMS7857 and SSTV16857 are currently sampling with production slated for the third quarter. The FM34W02 will be available for sampling in the third quarter and production is scheduled for the fourth quarter of this year. The FMS7857 is available in a 48-pin TSSOP package and is priced at $4 each in 1,000-piece quantities. The SSTV16857 is offered in the 48-pin TSSOP package and is priced at $4.25 each in the same quantities. The FM34W02, also in 1,000-piece quantities, is offered in the 8-pin TSSOP and SOIC packages, and is priced at 80 cents each.
