Agiga Tech Inc., a subsidiary of Cypress Semiconductor, is extending its Agigaram non-volatile RAM system with the release of CAPRI family, which delivers densities between 256MByte and 2Gbyte. The product family leverages a DDR2 SDRAM interface to deliver speeds up to 800MHz with peak transfer rates equivalent to DRAMs. It enables zero standby power, power interruption immunity, instant on/recovery, write caching/posting, data logging, service/maintenance processing, journaling, unified memory architectures and UPS replacement/redundancy. The products provide all these features while preserving mission-critical data.

The Agigaram is suited for a wide range of applications, including storage, networking, communications, industrial computing and controls, medical equipment, gaming systems, ATMs and point-of-sale terminals, printers, scanners, copiers, automotive and military systems.

"The CAPRI family brings Agigaram's unique high-speed, high-density non-volatile RAM technology to higher-end applications in the networking, storage, industrial and embedded markets," said Ron Sartore, CEO of Agiga. "Our flexible CAPRI products come in multiple form factors and host interfaces, enabling rapid time-to-market and high performance."

Until now, high-speed, non-volatile memory choices have been limited, especially when the performance of a RAM is desired. Complementing the non-volatile SRAM offerings from Cypress, the Agigaram system scales and extends nonvolatile solutions to much higher densities. The next best high-density alternative, battery-backed memories, can offer high speeds, but are subject to numerous problems, such as hazardous material issues, increased design complexity, long charge times, limited operating life, and a high total cost of ownership.

The Agigaram system solves these problems with a novel use of a battery-free power sub-system, teamed with high-speed synchronous DRAM, NAND flash, intelligent power management and a proprietary system controller. During normal operation the Agigaram functions exactly like an SDRAM. When power is lost, however, it automatically saves the data to NAND flash using the energy stored in the power subsystem. When power is restored, the data is transferred back into the SDRAM. This functionality can be used for power interruption/loss immunity, instant-on recovery, write caching and posting, data logging and journaling, and service and maintenance processing.

Targeted at higher end storage, industrial, networking, and communications applications, the products come in 256MByte, 512MByte, 1GByte and 2GByte densities. The 64/72bit DDR2 SDRAM interface offers high speeds of 533-, 667- and 800MHz. They enable 6,400MBps peak transfers and support I?C command/control bus. They come in 244-pin mini-RDIMM, 240-pin RDIMM and custom form factors and operate at the 0-60C operating range, with additional ranges available. There is a choice of 5-year and 10-year operating life options and an integrated battery-free power pack.

The Agigaram CAPRI product family is sampling now, with production expected in Q4 09. The PLUM PCI-CAPRI Evaluation kit is on sale now.
