What is the life expectancy of Micron's Mobile LPDRAM products?
We're excited about this fast-growing market. We plan to manufacture Mobile LPDRAM for many years to come and plan to continue to shrink our designs to achieve higher densities.
What is Mobile LPDRAM?
Optimized for products where power consumption is a concern, our low-power Mobile LPDRAM devices combine leading-edge technologies and packaging options to meet space requirements and extend battery life. Mobile LPDRAM is available with DDR/SDR interface.
The part I was using is obsolete and the replacement is a faster speed grade. Can I run the Mobile LPDRAM parts at a lower speed?
Yes. A Mobile LPDRAM part can be run at any speed equal to or slower than its rated speed grade.
What makes Micron's Mobile LPDRAM unique?
We offer a comprehensive Mobile LPDRAM product portfolio, with a wide range of densities and package options (including JEDEC-standard VFBGA, Known Good Die, and package-on-package). With nearly a decade of Mobile LPDRAM experience, our worldwide technical support team can provide the expertise and assistance you need to get your designs to market faster.
Where are Micron's Mobile LPDRAM products used today?
Our Mobile LPDRAM products are used in a wide variety of applications. The most popular are consumer electronic devices like digital still cameras and MP3 players, as well as mobile phones and PDAs. Automotive, medical, and military companies, which are very stringent on quality and reliability, use Mobile LPDRAM to take advantage of the wide industrial temperature range of –40°C to +105°C, which other memory vendors don’t support. It’s also designed in to a variety of networking applications.
What Mobile LPDRAM parts have been validated on the OMAP35x?
Micron works closely with Texas Instruments (TI) to validate and optimize our parts for the OMAP35x processors. As we work with the OMAP35x team, the list of validated memory devices expands frequently. For the most current information, contact your local Micron support, or contact Micron Product Sales Support
Do you recommend a x8, x16, or x32 configuration for mobile applications?
Mobile LPDRAM is offered in x16, x32, and x64. To make the best Mobile LPDRAM choice, consider the application, bandwidth/throughput, physical space on the PCB, and power consumption.
Are your Mobile LPDRAM parts JEDEC-compliant?
We design our parts to meet or exceed the JEDEC specification. As standards change, we will make the necessary changes to ensure our parts meet new specifications. Any changes made will be noted in a product change notice (PCN) and sent to our customers.
Are Micron's Mobile LPDRAM products green/RoHS compliant?
Yes. Micron’s green engineering program is RoHS-compliant and conforms with most of the world’s emerging environmental standards, including those in Asia and Europe.
Does Micron's Mobile LPDRAM cost more than standard DRAM?
It depends. Density plays a major role in price comparisons between Mobile LPDRAM and standard SDR/DDR. Also, since Mobile LPDRAM is offered in standard configurations of x16, x32 and x64, you may be able to reduce your overall BOM cost if your application currently uses two x16 components to support a x32 bus. You could use one x32 Mobile LPDRAM instead of two x16 standard DRAM. Contact your local rep for cost information.
Is Mobile LPDRAM a growing market?
Absolutely. iSuppli estimates that the market for Mobile LPDRAM is growing rapidly, with a CAGR of 21.2% from 2006 to 2011. We’re continuing to develop advanced Mobile LPDRAM solutions to meet this growing market.
How does LPDDR3 differ from LPDDR2?
LPDDR3 increases performance to 1600 Mb/s (versus 1066 Mb/s for LPDDR2). Additional changes include write leveling, C/A (command/address) training, and a lower I/O capacitance limit to improve timing.
How does LPDDR3 differ from DDR3L-RS?
LPDDR3 is optimized for battery life and portability. DDR3L-RS is a low IDD6 version of the DDR3L die and offers a balance in price versus performance, along with improved standby power.
What’s the difference between Mobile DRAM and Mobile LPDRAM?
There is no difference; Mobile DRAM and Mobile LPDRAM are the same product. We opted to add the "LP" prefix to our Mobile DRAM product line to align with the common terminology used throughout the industry and to ensure our customers know at a glance that our Mobile DRAM is a low-power memory device. In addition to the family name change, Mobile DDR SDRAM and Mobile SDR SDRAM are now called Mobile LPDDR and Mobile LPSDR, respectively.
Our Web site has been wholly converted to the Mobile LPDRAM naming convention, but because we’re updating our PDFs as they come up for review you may see a few older technical documents that still use the old Mobile DRAM terminology.
