Fujitsu Microelectronic has introduced a 256-Mbit consumer FCRAM featuring low power and high throughput for digital consumer electronics products.
The MB81EDS256545 runs on 1.7V to 1.95V and is intended for system-in-package (SiP) designs that feature small mounting spaces on circuit boards and reduced component costs. A 64-bit I/O, low-power DDR SDRAM interface enables data transfer rates equivalent to two DDR2 SDRAMs with 16-bit I/O. The FCRAM reduces power consumption by a maximum of approximately 1 watt (1W), which is equivalent to about 70 percent less power than is required in typical implementations.
The FCRAM eliminates the need for resistors by using a wide 64-bit I/O bus, so that it can run at a lower operating frequency. The result is performance equivalent to two 16-bit DDR2 SDRAMs with 16-bit I/O interfaces, with about one full Watt less total power consumption.
With a 64-bit-wide I/O and operating frequencies up to 216MHz, this product has a maximum data transfer rate of 3.46 gigabytes per second. This makes it well-suited for processing of image/video data and other data types that require high bandwidth, such as digital television. Pricing: Samples are $10 each.
