Alliance Memory adds DDR3 and DDR3L SDRAMs in 78- and 96-ball FBGAs
Alliance Memory has expanded its high-speed CMOS DDR3 and low-voltage DDR3L SDRAM offering, with 512Mbit x8 and x16 devices in the 78- and 96-ball FBGA packages, respectively.
Featuring a DDR architecture, the SDRAMs provide extremely fast transfer rates of 1600Mbit per second and clock rates of 800MHz, says Alliance Memory.
“Very few suppliers offer 512Mb DDR3 and DDR3L SDRAMs, so we are excited to add them to our broad lineup, which also includes hard-to-find 8Gbit devices,” said TJ Mueller, vice president of marketing at Alliance Memory. The DDR3 and DDR3L SDRAMs are offered in the same FBGA packages as devices with densities from 512Mbit to 8Gbit, allowing customers to switch easily if more memory is required.
With minimal die shrinks, the devices released today provide reliable drop-in, pin-for-pin-compatible replacements for similar solutions used in embedded systems, desktop and notebook computers, industrial metering applications, consumer electronics, and wireless basestations, says Alliance Memory, pointing out that this eliminates the need for redesigns and part requalification.
The 512Mbit DDR3 SDRAMs operate from a single +1.5V (±0.075V) power supply, while the DDR3L SDRAMs operate from a single +1.35V power supply, with backward compatibility to 1.5V. The JEDEC-compliant devices are available in commercial (0 to +95 degree C) and industrial (-40 to +95 degree C) temperature ranges
The DDR3 and DDR3L SDRAMs support sequential and interleave burst types with read or write burst lengths of four or eight. An auto pre-charge function provides a self-timed row pre-charge initiated at the end of the burst sequence. Refresh functions include auto- or self-refresh. The devices are RoHS-compliant, being lead- and halogen-free.
Samples and production quantities of the 512Mbit DDR3 and DDR3L SDRAMs are available now, with lead times of eight weeks.
Alliance Memory provides critical and hard-to-find DRAM and SRAM ICs for the communications, computing, consumer electronics, medical, automotive, and industrial markets. The company’s product range includes DRAMs and SRAMs with commercial, industrial, and automotive operating temperature ranges and densities from 64kbit to 8Gbit.
