Manufacturer of Legacy Memory SRAM, DRAM, AND SDRAM ICS

| June 2014|


We've just introduced a new line of high-speed CMOS double data rate 3 synchronous DRAMs (DDR3 SDRAM) and low-voltage DDR3L SDRAMs with densities of 1 Gb, 2 Gb, and 4 Gb in 78-ball 9 mm by 10.5 mm by 1.2 mm and 96-ball 9 mm by 13 mm by 1.2 mm FBGA packages. With their double data rate architecture, our new DDR3 SDRAMs offer extremely fast transfer rates of up to 1600 Mbps/pin and clock rates of 800 MHz.

With minimal die shrinks, our DDR3 and DDR3L SDRAMs provide reliable drop-in, pin-for-pin-compatible replacements for a number of similar solutions that work with microprocessors in industrial, consumer, and telecom applications — eliminating the need for costly redesigns and part requalification. The new parts come with different voltage and temperature options.

The AS4C64M16D3, AS4C128M8D3, AS4C128M16D3, AS4C256M8D3, AS4C256M16D3, and AS4C512M8D3 DDR3 SDRAMs operate from a single +1.5-V (±0.075 V) power supply, while the AS4C64M16D3L, AS4C128M8D3L, AS4C128M16D3L, AS4C256M8D3L, AS4C256M16D3L, and AS4C512M8D3L DDR3L SDRAMs operate from a single +1.35-V power supply. The devices are offered with a commercial temperature range of 0 °C to +95 °C and an industrial temperature range of -40 °C to +95 °C.

The Company

A provider of electronic product manufacturing services, Plexus uses a unique Product Realization service model to transform its customers' concepts into branded products and deliver them to target markets. Tailoring innovative solutions that integrate product conceptualization, design, commercialization, manufacturing, fulfillment and sustaining services, the company serves a worldwide base of customers delivering turnkey solutions that make electronic products a success.

The Challenge

Plexus customers come from most major industries using electronics, including networking and communications, healthcare/life sciences, test and measurement, control automation, energy and energy management, point-of-sale systems, defense, security, and aerospace. Most of these in turn require memory ICs for new and existing designs, so having reliable sources of legacy products such as those manufactured by Alliance Memory is key to the Plexus business model.

The Customer

"We use products from Alliance Memory pretty much across all of our market segments — and all of them need both SRAMs and DRAMs," says Todd Donnermeyer, Global Commodity Manager at Plexus. "Not only does Alliance Memory provide us with an alternate source from a cost reduction standpoint, they excel in quality and service. They understand the importance of keeping key components available and have done well in continuing to add to their product portfolio as other manufacturers EOL various products. In my experience they've been very easy to work with and ready to go above and beyond."


If it seems to you that end-of-life (EOL) notices for memory chips are becoming more common, you're not just imagining things. Not only are more memory chips being EOL'd in terms of absolute numbers, it's happening at an earlier point in the component life cycle. There are a number of reasons for this. One is the pace of innovation in consumer electronics, which is moving faster than ever. Another driver is the imperative to reduce costs — and fill up fab capacity — with die shrinks. Of course, it's understandable that consumers want the newest and fastest gadgets, and that companies who have invested in new fabs don't want them to sit empty. But there's a whole world of electronic products out there, from ATMs to industrial control systems to cash registers, for which a relatively brief component life cycle is never going to make any sense. That's why Alliance Memory remains firm in our commitment to providing our customers with memory ICs that help them avoid costly redesigns. Meanwhile we're continually expanding the categories of memory ICs that we offer. If your design needs to last 10 years instead of 10 months, then you've come to the right place.
