AgigA Tech has introduced the DDR3-registered DIMM as part of its family of enhanced speed, battery-free non-volatile RAM systems. This feature in the AGIGARAM non-volatile system family delivers densities up to 8Gbytes providing flexibility to system architects and designers to tailor non-volatile memory for specific application requirements. The product family merges NAND flash, DRAM and a battery-free ultracapacitor power source into a reliable, non-volatile memory system. When used as a write cache in enterprise-class applications, the system provides a performance-boosting building block and guards against power failures and consequent loss of critical data. The DDR3 products deliver data transfer speeds up to 1333MTPS. The company offers product support to boost reliability, including extensive ultracapacitor testing with a test lab, in-system health monitoring, a system safe control protocol, and product assurance up to the operating life of the system. The next high-density alternative, battery-backed memories can offer enhanced speeds but are subject to problems such as hazardous material issues, increased design complexity, long charge times, limited operating life, and high total cost of ownership, claims the company. The system solves these problems with use of a battery-free power sub-system teamed with enhanced SDRAM, NAND flash, intelligent power management and a proprietary system controller. During normal operation, the system appears as a DDR3-registered DIMM to the host system, providing the benefits and speed of a standard high-speed and high-density SDRAM. In the event of a power loss, the system can be commanded to take control of the SDRAM and transfer its contents to a flash memory using energy from its ultracapacitor power source, thereby preserving all the SDRAM data. After power is restored, the system can be commanded to transfer the contents back into the SDRAM and returns control to the host system. This functionality can be used for power interruption/loss immunity, write caching and posting, data logging and journaling, instant-on recovery, and service and maintenance processing.
