Hynix licenses ISi’s Z-RAM memory for DRAM products

SANTA CLARA, USA & ICHEON, KOREA: Innovative Silicon Inc. (ISi), the developer of Z-RAM high-density memory intellectual property (IP), and Hynix Semiconductor Inc. announced that Hynix has agreed to license ISi’s Z-RAM for use in its DRAM chips.

Z-RAM-based DRAMs will use a singletransistor bitcell -- rather than a combination of transistors and capacitor elements -- representing the first fundamental DRAM bitcell change since the invention of the DRAM in the early 1970s. Hynix has received the first-mover opportunity to bring Z-RAM to the DRAM market. To ensure this advantage,the two companies have committed considerable engineering resources to work side-by-side on the program.

Z-RAM was initially developed as the world’s lowest-cost embedded memory technology for logic-based ICs such as mobile chipsets, microprocessors, networking and other consumer applications The technology was first licensed, in December 2005, by AMD for upcoming microprocessor designs. Now, the engagement with Hynix positions Z-RAM to become the lowest-cost memory technology in the greater than $30bn memory market.

Sung-Joo Hong,VP of R&D Division at Hynix, said: "Z-RAM promises to provide an elegant approach to manufacture dense DRAMs on nanometer processes. We see the potential to create a new platform of products based on ISi’s innovation of Z-RAM that will help us maintain and grow our leadership position in the memory market."

Mark-Eric Jones, ISi CEO, noted: "Hynix’s decision to collaborate with ISi is additional validation of the strength and commercial viability of our Z-RAM memory technology, particularly since Hynix is a dominant player in the memory IC market and its products are used in a vast array of electronic devices, including personal computers, servers, workstations, graphic cards, as well as handheld devices, such as mobile phones, MP3 players and digital cameras. Memory chips built using ISi’s Z-RAM technology will be much smaller and cheaper to manufacture. We are looking forward to workingwith Hynix on its next generation of DRAM chips, and to bringing tremendous performance and usability advantages to end-users."

Jeff Lewis,VP marketing at ISi, added: "We believe that this is a major milestone for ISi and Hynix. Z-RAM will have a profound impact on the way DRAMs are designed and manufactured. Since the DRAM industry sold more than $33 billion worth of products in 2006, these developments will, in turn, significantly affect the electronics industry as a whole."

ISi’s Z-RAM stands apart from today’s standard DRAM and SRAM solutions as its single transistor (1T) bitcell architecture is the world’s smallest memory cell, making it the highest density, and therefore, the world’s lowest-cost semiconductor memory solution.

Z-RAM’s one transistor memory bitcell is made possible by harnessing the Floating Body Effect (FBE) found in circuits fabricated using SOI (silicon-on-insulator) wafers.  Moreover, since Z-RAM takes advantage of a naturally-occurring SOI effect, Z-RAM does not require exotic process changes to build capacitors or other complex structures within the memory bitcell.
