Fujitsu Launches Low-Power Consumption 256Mbit FCRAM for Digital Consumer Electronics
Key features include a 64-bit I/O, a low power DDR SDRAM interface that enables data transfer capabilities equivalent to two DDR2 SDRAMs with 16-bit I/O while reducing power consumption by up to 1W (equivalent to approximately 70%). This contributes to power savings for digital consumer electronics and makes the new device ideal for consumer electronics products that require low power consumption, such as digital televisions and camcorders.
In recent years, while the electronic components that drive digital consumer electronics have become higher in performance and feature integrated functionalities, an issue to overcome had been how to handle the rise in heat generation, attributable to smaller chips and efforts made to make consumer electronics more power-efficient. This has led to a need for components with low power consumption.
Fujitsu Microelectronics' new FCRAM features significantly reduced power consumption by approximately 70%. This power saving helps reduce the power consumption for consumer electronics, while better heat dissipation simplifies product development and lowers component costs.
Fujitsu anticipates that this memory can replace conventional RAMs for use in digital consumer electronics that require lower power consumption, such as digital televisions and camcorders, and will provide solutions featuring ideal product value and cost.
Data transfer on par with DDR2 SDRAM on maximum 1W less power consumption
DDR2 SDRAM and other high-speed memory interfaces require termination resistors to maintain stable signals, which consume much electricity. The new product uses a wide 64-bit I/O, so that it can run at a lower operating frequency and dispense with termination resistors, resulting in performance equivalent to two DDR2 SDRAMs with 16-bit I/O, while requiring about 1W less power consumption, or a 70% reduction (see Figure 1 - link below).
High-speed processing of large-scale image data at double the performance speeds of DDR2 SDRAM
With a 64-bit-wide I/O and operating frequencies up to 216MHz, this device has a maximum data transfer rate of 3.46GB per second, double that of typical DDR2 SDRAM. This makes it well-suited for processing of image/video data and other data types that demand high bandwidth, such as digital television.
Memory designed for SiP helps conserve mounting space
This product is designed to be integrated with logic chips into a SiP, thus requiring less mounting space on circuit boards and thereby reducing costs for components and the board material itself. In addition to being offered in a wafer form for SiP integration, Fujitsu's new FCRAM is also offered as a wafer level package (WLP) (see Figure 2 - link below).
