New Memory Chip Source In Face Of Market Shortages

Alliance Memory Introduces New Die Version for 2Gb and 4Gb DDR3 and DDR3L SDRAMs; Provides New Memory Chip Source in Face of Market Shortages

Alliance Memory today announced a new die revision (B die) for its 2Gb and 4Gb devices in the 96-ball FBGA package to address the memory market’s shortage of high-speed CMOS DDR3 and low-voltage DDR3L SDRAMs.

Due to their increased functionality and speed, Market demand for DDR3 and DDR3L SDRAMs is extremely high, but their availability is becoming more and more limited as demand exceeds supply and suppliers move capacity to Flash and other products. Alliance now have two sources for our 2Gb and 4Gb parts’ silicon, with the introduction of a new B die version. This means our customers can be more confident than ever in our ability to deliver these devices despite shortages and price increases in the memory market.

Alliance Memory’s DDR architecture of 2Gb and 4Gb DDR3 and DDR3L SDRAMs allows them to achieve extremely fast transfer rates of 1600Mbps and clock rates of 800MHz. With minimal die shrinks, the devices provide reliable drop-in, pin-for-pin-compatible replacements for a number of similar solutions used in newer-generation microprocessors for networking, industrial, medical, telecom, and consumer applications — eliminating the need for costly redesigns and part requalification.

The 2Gb AS4C128M16D3B-12BCN and 4Gb AS4C256M16D3B-12BCN DDR3 SDRAMs operate from a single +1.5V (±0.075V) power supply, while the 4 Gb AS4C256M16D3LB-12BCN DDR3L SDRAM operates from a single +1.35V power supply. The devices offer a data mask for write control and are available with a commercial temperature range of 0°C to +95°C. The 4Gb DDR3L SDRAM is also available in an industrial temperature range of -40°C to +95°C.

The 2Gb DDR3 SDRAMs are internally configured as eight banks of 16M word x 16 bits, while the 4Gb DDR3 and DDR3L SDRAMs are configured as eight banks of 32M word x 16 bits. All devices support sequential and interleave burst types with read or write burst lengths of 4 or 8. An auto pre-charge function provides a self-timed row pre-charge initiated at the end of the burst sequence. Easy-to-use refresh functions include auto- or self-refresh. RoHS-compliant, the devices are lead (Pb)- and halogen-free.

Inclusion In The European Standard List -AEM’s High-Reliability Solid Body Fuses Added To European Preferred Parts List (EPPL)

The semiconductor fuses of the product line FM12 (QPL) of the Californian component manufacturer AEM were selected by the European Space Components Coordination(ESCC) for inclusion in the European standard parts list (EPPL), which is a milestone of AEM’s commitment to quality ; 30-year zero-defects history is unrivaled in industry.
The FM12 Series fuses, also included on the Defense Logistics Agency Qualified Products List (QPL), are intended for use in a wide variety of aerospace applications that require the highest level of reliability.

The semiconductor fuses are equipped with a precise thick-film melt element with a glass arc suppression system which ensures that arc, plasma and steam are trapped inside the fuse housing under overload conditions. The positive temperature coefficient of the fuse element causes a resistance increase (before opening), thus preventing a total short circuit of the current source. The components are approved for operation at temperatures between -55 and + 125 ° C. No current or voltage derating is required when operating in a vacuum.
With over 30 years in orbit with zero reported failures, AEM fuses have long been recognized and utilized by every major producer of satellites and spacecraft hardware. And now they are also recognized by the European Space Agency as a qualified parts provider.

AEM’s MIL-STD-790 and AS9100 certified facility in San Diego, Calif., will continue to provide unique component solutions to meet mission critical program needs.

Karl Kruse Supports You In Component Obsolescence Management

There has been enough advice on managing obsolescence and obsolescence or end-of-life, and has been a hot topic of discussion in recent years. We all know that these critical events can be significant procurement challenges, including the continuity of manufacturing, quality, cost management and support: not to mention the future maintenance costs.

Especially in devices and systems with a life cycle of more than ten years, experts assume that up to 50 percent of the total product cycle costs are now caused by direct or indirect obsolescence effects.

When selecting a device exchange based on the original system design as well as customer requirements such as cost and time, or function and environment parameters, there are typically limitations. Also, there may be problems with industry certifications, matching components for identical drop-in capability, and delivery problems during the product life cycle.

When EOL events occur, we are often discussing how collaboration across the supply chain can turn the procurement, replacement, or design challenges into a problem. This is true. Partnerships between end-product manufacturers, original component manufacturers and distributors can lead to appropriate short-term supply chain options for the device running EOL. Sales partners can also stand in line with retrofit and replacement solutions.

Through components with shorter life cycles and beyond, we read how the interruption of the production of materials, components and devices is a part of everyday production. The industry knows that every material, product and technology has a life cycle. As product demand falls to smaller volumes, it becomes unprofitable to continue producing a specific part or series, is only a matter of time before the manufacturer discontinues the production of a part.

In order to minimize the impact of the inevitable product break-up and that OEMs have to strategically plan for an EOL event to keep their own production lines in operation, we need to find solutions.
The counterfeiting is a major problem in the electronics world that is only exacerbated by EOL events, we also know. Today even less demanding, more costly parts are falsified. To ensure product quality is working with an authorized supplier with a proven product authenticity and traceability to the original manufacturer is required, procurement professionals also understand.

Unfortunately, what we are not talking about, end -of-life. The partnership with a specialist for the procurement of obsolete components and original component manufacturers, which has no obsolescence policy, is the most suitable solution for CEMs and OEMs. Component manufacturers who have made these promises to their customers are few, but some have committed themselves to doing so.

As an obsolescence specialist, Karl Kruse GmbH & Co KG has been working on the optimization of obsolescence strategies for many years. Solution approaches are in focus, starting with the research of alternative components, 100% traceability of the components, as well as protection against obsolescence such as EOL and PCN services and last time buy etc.

Alternative components are offered by Karl Kruse of various manufacturers and is also an authorized distributor for Calogic, Etron, Orion fans and others.

Calogic offers a range of reliable and long-lasting standard replacement diodes, JFETS and MOSFETs. Just the canceled JFETS from Vishay / Siliconix, are available from Calogic. Calogic designs and manufactures discrete and analog ICs for the use of automotive, automation, computers, instrumentation, medical applications, power management, transportation and telecommunications and others.

“We have been able to find an alternative to the NXP MOSFET BSS83, which has been discontinued, and have been able to qualify them for their OEMs in the automotive and industrial industries “says Klaus Kruse.

Etron and Alliance Memory offer DRAMs and SDRAMs storage solutions for industrial, automotive, medical and consumer areas.

The largest selection of AC fans, DC fans, fan feeders, fan accessories and blowers, Orion offers fans. With the fastest response time, the largest available inventory, the shortest delivery times and competitive prices, Orion fans deliver exactly the cooling solution you need – faster than anyone else.
Automotive manufacturers and manufacturers who develop and produce durable industrial goods such as medical equipment, railway technology or production machines are among our customers. In the forefront of this, 1 customers from all automotive and industrial segments will be present.

There are many pain points in the design and manufacturing process. End-of-life announcement should not be another point of concern.
