Samsung Electronics Develops First 128Mb SDRAM with DDR/SDR Manufacturing Option

Seoul, South Korea - February 10, 1999 - Samsung Electronics Co., Ltd. has completed development of a 128Mb Double-Data-Rate Synchronous Dynamic Random Access Memory (DDR SDRAM) device, which is a second-generation enhancement to the 128Mb PC100 SDRAM introduced by Samsung in 1998. This new product is an indication of Samsung's belief that support of existing synchronous DRAM product lines can continue, providing customers with evolutionary solutions while introducing new DRAM technologies like RambusO DRAM devices.

Last June, Samsung Electronics became the first in the industry to come out with a 64Mb DDR SDRAM and samples were shipped to the world's major computer manufacturers.
New products using DDR SDRAMs are currently under development. Now that Samsung has completed a 128Mb DDR device, the company has gained a technological and time-to-market advantage in both Rambusa DRAMs and Synchronous DRAM offerings.

Samsung's 128Mb DDR chip processes data at 266MHz; 26 million characters can be transmitted per second. In a system with a 64-bit-wide memory bus, that's 2.13Gb per second peak bandwidth. Bandwidth can be increased with wider buses.

Power consumption is about 0.5W (active) because of a low 2.5 volt power supply and SSTL_2 interface. This is especially helpful in systems using many DRAMs because total power consumption and heat can present significant design challenges both for the system designer as well as the chip designer. A 1.2Gb system using 64, 128Mb DDR SDRAM devices would have a memory power consumption under 7W.

Finally, the 128Mb DDR SDRAM operates using a memory bus clock of 100MHz or 133MHz, the same speeds as PC100 and PC133 SDRAMs. This is significant to the system designer in that common motherboard infrastructure components are used and motherboard design rules are understood in production today.

Additionally, a significant benefit to the customer is that a one-chip DDR/SDR design allows the new product to support both PC100 and the new PC133 standard Single-Data-Rate SDRAMs as a fabrication manufacturing option for maximum customer flexibility. The company plans to begin mass producing the 128Mb DDR SDRAM version along with the 64Mb version in the second half of 1999.

Samsung Electronics is leading the way for standardizing DDR SDRAMs. It has endorsed and adopted new DDR standards proposed by the Joint Electronics Device Engineering Council (JEDEC). The company expects to be an early leader supplying to the DDR market in the second half of 1999.

According to Managing Director Soo-in Cho of the Samsung Electronics DRAM Design Laboratory, "We have completed development of new next-generation, standard products such as DDR SDRAM, Rambus DRAM and PC133 SDRAM and have mass-production capability in place."

Samsung Electronics Co., Ltd. with 1998 sales revenue of more than 17 billion dollars (US) is a world leader in the electronics industry, with operations in more than 50 countries and 60,000 employees worldwide.
The company consists of three main business units:Multimedia & Home Appliances, Semiconductors and Information & Telecommunications. For more information, please visit our website, http://www.samsungelectronics.com.
