6/28/2002 - Ramtron International Corporation (Nasdaq: RMTR) subsidiary Enhanced Memory Systems, Inc. announced today that samples and pre-production quantities of its 72Mb No Bus Latency (NoBL) Burst Enhanced SRAM (ESRAM) are now being delivered to customers. The new 72Mb NoBL ESRAM, which uses Enhanced’s proprietary one-transistor Enhanced SRAM (ESRAM) architecture, is the highest-density SRAM replacement product available.
“We are now providing samples and pre-production quantities of our 72Mb NoBL Burst ESRAM to customers," said David Bondurant, vice president of marketing for Enhanced Memory Systems. “This product family sets new benchmarks for SRAM density, price per bit, and low-power consumption.”
Enhanced Memory Systems also disclosed that its one-transistor ESRAM, which uses an advanced trench DRAM process, provides a significant improvement in soft-error performance over both high-density SRAM and embedded SRAMs built on logic-based CMOS processes. Details are posted on the company’s website at www.edram.com.
“Testing of the trench capacitor process shows very low soft-error rates compared to current high-density SRAM and logic-based one-transistor SRAM products,” said Dave Fisch, Enhanced business vice president. “This performance is driven by the Infineon technology used to manufacture our products as well as our patented architecture. As a result, we expect a significant soft-error advantage.”
System failures due to soft errors have become a growing concern in the SRAM industry. Soft errors occur when an alpha particle emitted by materials in semiconductor packaging or naturally occurring neutrons from cosmic rays disturb a memory storage cell, causing a loss of stored data. As six-transistor SRAMs are scaled to higher densities, they become increasingly susceptible to soft errors. The NoBL Burst ESRAM provides a significant reduction in soft errors due to its high-capacitance trench capacitor and unique one-transistor SRAM architecture. SRAM users can now enjoy the speed and performance of SRAM in leading-edge densities without the reliability concerns associated with high-density conventional SRAMs.
The 72Mb NoBL Burst SRAM products are organized 2 Mb x 36, operate at up to 166 MHz clock speed and deliver 100-percent bus bandwidth during four-word read-write transactions. The products are available with 2.5V or 3.3V power supply options and 100-pin TQFP and 119-pin PBGA packaging options. 72Mb NoBL is pin-compatible with existing 18Mb NoBL or ZBT SRAM products to allow multiple SRAMs to be replaced with a single lower-cost, lower-power ESRAM. Samples are priced at $80 each in small quantities and are available immediately. The products are pin-function and timing-compatible with NoBL SRAMs, making them ideal upgrades in network systems that require larger SRAM buffer memories.
About Ramtron/Enhanced Memory Systems
Ramtron is the world leader in ferroelectric random access memories (FRAM?) products -- new high-performance nonvolatile memories that merge the benefits of many mainstream memory technologies into a single device. The company also develops and markets ultra-high performance memory products through its subsidiary, Enhanced Memory Systems, Inc. Ramtron holds more than 50 international and U.S. patents covering its proprietary technologies.
Enhanced Memory Systems became the world’s first specialty DRAM Company when it announced the Enhanced DRAM (EDRAM) in January 1992. Enhanced was the first company to combine a fast DRAM and SRAM row register cache on one chip to minimize DRAM latency and increase real bandwidth in systems. Millions of EDRAM products have been delivered to leading communications, RAID disk controller, embedded computer, DSP, PC system, and 3-D graphics companies. As a fab-less DRAM manufacturer, Enhanced develops unique, patented high-performance products and manufactures them with leading DRAM wafer, packaging, and test sub-contractors worldwide. During 2001, Enhanced announced the world’s highest-density SRAM replacement products based on patented one-transistor Enhanced SRAM technology.
