ALLIANCE MEMORY ENTERS SDRAM MARKET

New High-Speed CMOS Synchronous DRAMs

Alliance Memory has just launched a new family of CMOS synchronous DRAMs (SDR) with densities of 64 Mb (AS4C4M16S), 128 Mb (AS4C8M16S), and 256 Mb (AS4C16M16S).

The new SDRs are optimized for industrial, communications, medical, and consumer products requiring high memory bandwidth, and are particularly well-suited to high-performance PC applications. Internally configured as four banks of 1M, 2M, or 4M word x 16 bits with a synchronous interface, the SDRs operate from a single +3.3-V (± 0.3V) power supply, and are lead (Pb)- and halogen-free.

Packaged in a 54-pin, 400-mil plastic TSOP II, the new SDRs offer a fast access time from clock down to 4.5 ns at a 5-ns clock cycle, and clock rates from 143 MHz to 200 MHz.

Our SDRs provide programmable read or write burst lengths of 1, 2, 4, 8, or full page, with a burst termination option. An auto pre-charge function provides a self-timed row pre-charge initiated at the end of the burst sequence. Easy-to-use refresh functions include auto or self refresh, while a programmable mode register allows the system to choose the most suitable modes to maximize performance.

NEW EUROPE AND ASIA OFFICES EXTEND ALLIANCE MEMORY'S WORLDWIDE PRESENCE

Alliance Memory is extending its worldwide presence with the opening of offices in the United Kingdom and Taiwan.

Our U.K. office is being headed up by Sue Macedo, who has been appointed as sales director, Europe. In her new role, Macedo will work closely with the sales team in supporting Alliance Memory's European client base and promoting the company's SRAM and synchronous DRAM products. In Taiwan, William Chen has joined the company as our new director of sales responsible for supporting Alliance Memory's distributors and promoting the company's SRAM and synchronous DRAM products in Taiwan and China, a territory that will expand to all of Southeast Asia.

Macedo has more than 25 years of management expertise within multi-million-dollar corporations and a wide range of business organizations. She originally came to Alliance Memory in 2005 when the company acquired the asynchronous SRAM business from Alliance Semiconductor, where she held the position of sales and marketing director, EMEA. Sue is based near London on the south coast of the United Kingdom, and reports to Dan Gilbert. You can reach her at sue@alliancememory.com.

Chen has worked in the semiconductor field since 1997, holding key positions in distributor and product line management. He comes to Alliance from Linpo – an Alliance Memory distributor located in Taiwan – where he served as sales manager for worldwide distributors of the GTM brand and product manager for Alliance Memory, among other manufacturers. Previously, he has held sales management position at Cosmo Electronics Corp., E-Tech Electronics, and Unisonic Technologies Co. Ltd. William speaks fluent French, English, Mandarin, Hakka, and Taiwanese, in addition to limited Cantonese, Korean, and Japanese. You can reach him at william@alliancememory.com.
 


FINAL WORD: FROM THE PRESIDENT

For the past several weeks the world has been watching with concern the after effects of the Japan earthquake and tsunami. We would like to reassure our customers that Alliance Memory expects no impact on our supply chain or business from the situation in Japan, where none of our manufacturing and assembly operations are located. While it is possible other suppliers may see a shortage of legacy memory chips in the next few months, once their finished goods inventory is depleted, Alliance Memory will not be affected.

—David Bagby, President and CEO


 

"As other suppliers are exiting the DRAM market to focus on new technologies, we remain committed to offering legacy parts to their customers, eliminating the need for costly redesigns of their end products. For these customers, it is imperative to have access to cost-effective drop-in replacement memory that is pin-for-pin compatible, and that is exactly what our new line of SDRs provides." — Dan Gilbert, Vice President of Sales


SYNCHRONOUS SRAM FAMILY NOW AVAILABLE

Alliance Memory offers a complete line of ZBT/Sync Pipelined burst (SPB)/Sync Burst (SB) SRAMs. These SRAMs are used with mainstream digital signal processors (DSPs) and microcontrollers found mainly in the digital consumer electronics, networking, mobile communications, industrial, and automotive electronics marketplace.
