Spansion`s ( http://www.spansion.com ) EcoRAM Solution architectural details about its energy-efficient Spansion® EcoRAM™ solution for data centers. The solution enables advancements in low power consumption, high performance and capacity, with the potential for eight to sixteen times more main memory in standard x86 servers. The solution is ideal for read-intensive applications in segments such as internet services, analytics, and business intelligence.
It creates a new class of memory for read-intensive applications in areas like internet services, analytics, oil and gas, government, bioinformatics, and business intelligence by employing an innovative memory subsystem architecture that enables advancements in low power consumption, high performance and capacity.
The Spansion EcoRAM architecture is designed to leverage existing and upcoming high-speed connectivity solutions from both Intel and AMD to improve performance. Because the architecture uses standard x86 servers with Spansion EcoRAM memory, commodity servers are able to potentially support an additional half Terabyte (512 Gigabytes) of main memory storage in a single standard form factor (1U) server using 32 Gigabyte Spansion EcoRAM dual in-line memory modules (DIMMs).
At the same time, this architecture is intended to deliver read performance of up to 4.0 Gigabytes per second (GB/s) in a 4-socket platform, which is comparable with DRAM read performance.
In terms of read latency, Spansion EcoRAM memory is expected to provide a read latency of 250 nanoseconds (ns) or less, compared to hard disk drives, which have far greater multi-millisecond latencies, or solid state drives which have multi-microsecond latencies. At the same time, write bandwidth capability of the architecture is projected at up to 300 MB/s, making it well- suited for read-intensive workloads in vertical market segments.
