DDR mobile RAM boosts speed and density
Elpida Memory has developed the industry's first 256Mbit double datarate mobile RAM components, along with a 256Mbit single datarate mobile RAM, both optimised for digital consumer products.
Elpida Memory has developed the industry's first 256Mbit double datarate (DDR) mobile RAM components, along with a 256Mbit single datarate (SDR) mobile RAM, both developed for digital consumer products such as mobile phones, PDAs, handheld PCs and digital cameras The high-density 256Mbit DDR mobile RAM devices offer a bandwidth of 400Mbyte/s

Sunrise set to ship fastest gate arrays yet
Dedicated NEC distributor Sunrise Electronics is now helping customers to design with the latest 0.25-micron CMOS-10HD family of CMOS gate array products.
CD covers full range of microcontrollers and tools
Available now free from Sunrise Electronics is a new CD featuring all the latest information on NEC's extensive range of microcontroller families and development tools.
Using Elpida's advanced-technology 0.11-micron process technology, the new DDR mobile RAM devices deliver a 90% power reduction compared with a standard 256Mbit DDR SDRAM, and a 10% space reduction compared with design implementations that use two 128Mbit mobile RAM devices, thus saving significant resources and cost for mobile applications.
Elpida's new mobile RAM devices have the part numbers: EDK2516CBBH (DDR) and EDL2516CBBH (SDR).
Each is organised as four banks of 4M x 16bit, and have a programmable burst length (BL) of two, four or eight.
The devices achieve both high-speed data transfer and low-power consumption, they operate on a low-voltage power supply of 1.8V +/-0.15V and are housed in 9 x 13mm small FBGA packages.
An auto-temperature-compensated self-refresh (ATCSR) function allows the devices' internal self-refresh timer to be set automatically, further reducing power consumption.
Auto TCSR eliminates the need for external operation/control because the die itself contains a temperature sensor that automatically changes the refresh duration.
Auto-refresh functions are offered at a rate of 8K refresh cycles every 64ms.
Additional features of the mobile RAM devices include a deep power down mode, programmable driver strength and partial array self refresh.
The products are also available as a "bare die" suitable for implementation in system-in-package or multichip-package designs.
The EDL2516CBBH 256Mbit SDR mobile RAM is sampling now in a 54-ball FBGA package, with volume production expected in August.
2003.
