Samsung Develops High-speed 128Mb DDR SDRAM samsungelectronics.com Jul 10, 2001 -Operating speeds of 2.4Gbps offers worlds fastest graphic performance. -Ultra-small FBGA chip scale or thin quad flat package options available -Dual-voltage(1.8V or 2.5 V) operation. -Mass production set for the 3rd quarter. SEOUL, Korea – July 10, 2001 – Samsung Electronics announces development of a 300MHz 128Mb (4Mb by 32) Double Data Rate synchronous DRAM (DDR SDRAM), part number K4D263238A-GC33. The new device is primarily intended for use in high-resolution graphics and high-speed video applications. Samsung believes that demand for this new product will extend to include notebook PC, wide-area network, local-area network, Internet router and switching memory, and Level 3 cache memory for high-end server applications. Samples are available now with mass production set for the 3rd quarter of 2001. Product configuration is 128Mb in a 4Mb x 32 configuration, operating at 300MHz which means the product can transfer data at 600Mbps. This gives a total operating speed of 2.4Gbps, a world fastest. This product follows closely on the Samsung 64Mb (4Mb x 16) product, part number K4D623238B-GC33, announced recently. Both parts are pin compatible, and can be used interchangeably depending on the memory capacity required. Samsung has included Fine-Pitch Ball Grid Array (FBGA) to the conventional Thin Quad Flat Package and chip scale packages (CSP), offering a wider range of solutions. The FBGA enables the device to run on 2.5 volts with a 1.8 volt Input / output option, greatly reducing power consumption. The demand for high-speed memory components is expected to increase, driven by the requirement to match systems utilizing CPU’s with clock speeds approaching 2GHz or higher which are now becoming commonplace in workstations, PC’s, and servers. Samsung plans to begin mass producing the new 128Mb DDR SDRAM in the third quarter of this year, bolstering the company’s the lead of the market for DDR devices used in networks and graphics cards. In the first quarter of this year, Samsung held 50% of the world DDR SDRAM market, and DDR memory represents the largest share of the world semiconductor market. Samsung also has 65% of the Rambus DRAM market as well.

Hi dumbmoney; Re: "This is wrong. RDRAM (any flavor) was never commonly used in graphics cards. Everyone was using SDRAM/SGRAM." I guess it depends on what one means by "commonly". (Or, perhaps, how soon we forget.) My original post on the subject: The History of Rambus and the Graphics Industry... With Links Bilow, SI RMBS thread, April 25, 2000 ... Back in 1995, it seemed pretty clear that Rambus was a natural for the graphics industry. And they did get some important design wins, but there was always a little hesitation in the industry. These first two stories are about concurrent Rambus DRAM design wins in graphics: ... #reply-13492784 I got this reply from John Farrell, who disagreed with some of my comments, but not on the fact that RDRAM was a disaster to the companies that tried it: John Farrell, April 25, 2000 "I worked in the PC graphics accelerator industry for seven (1991-1997) years for Radius, Headland Technologies (previously known as Video 7), Sierra Semiconductor and STB Systems working with various graphics ASICs from those companies or IBM (8514a & XGA), Western Digital (an 8514a clone), S3, Cirrus Logic, Tseng Labs, Nvidia and 3dfx and know the history of that industry and it's memory usage (DRAM, Fast Page DRAM, EDO DRAM, VRAM, SDRAM, MDRAM, SGRAM, Concurrent Rambus, and DDR DRAM) extremely well. ... As I said, in the PC Graphics industry, only Cirrus Logic (Laguna) and Chromatic Research (mPact) (which was founded by the same people who founded Rambus) used Rambus memory and neither one of them could compete on a price/performance basis with chips using EDO and SDRAM memory. The other graphics chip companies were reluctant to go with Rambus because it was next to impossible to do one design that would support Rambus memory AND EDO/SDRAM, partially because of the licensing fees on parts that never were used with Rambus memory. Rambus killed graphics at Cirrus Logic and they exited the business after having once been King of the heap (before they did their Rambus designs). ATI ended up buying Chromatic Research for it's DVD and system on a chip IP to put into set-top box designs (which use SDRAM)." #reply-13492979 lightner.net * GrafixStar 560 AGP - High-performance Windows 95 2D/3D AGP video accelerator card, 4 MB of high-performance Rambus (RDRAM) memory, Cirrus Logic CL-GD5465 high performance 64-bit 2D/3D controller, Windows 95/3.x/NT drivers, up to 1600 x 1200 * GrafixStar 560 PCI - 2D/3D high-performance graphics card, Cirrus Laguna GD5465 64-bit multimedia accelerator with 4 MB of ultra-fast Rambus (RDRAM) memory, Windows 95/3.x/NT drivers, up to 1600 x1200 techadvice.com August 26, 1998 Most higher-end gaming-oriented graphics chips use SDRAM, SGRAM, or RDRAM memory types because the memory is both fast and affordable enough to be installed in quantity. ... library.cs.tuiasi.ro library.cs.tuiasi.ro pctechguide.com -- Carl
