Is the Linux MTD good enough for MLC NAND flash?

On Linux, the Memory Technology Device (MTD) subsystem is designed to be a generic interface to memory devices, primarily Flash media. The integrated hardware driver handles the storage formats used on the media, and then MTD provides simple routines for block read, write and erase. MTD does not contain any bad block handling or wear leveling routines, so the use of MTD alone is not recommended on NAND flash media. Instead, developers are asked to use a full Flash File System on Linux, such as YAFFS, JFFS2 and UBIFS.

eMMC TRIM new to Android?

An August 1st blog post on Tom's Hardware reports that the new Android 4.3 NOW has support for the eMMC TRIM command. How odd that the Android OS that's on 80% of smart phones sold last quarter does not support eMMC TRIM for old deleted data, a feature which has been in the JEDEC specification since version 4.4 which was released in March of 2009.

SD Reliability - Best Practices

In an earlier blog post titled "Managed NAND Performance: It's All About Use Case," we referred to an article measuring SD media, specifically sequential write performance. Speed was measured using a camera to shoot continuous pictures. Photographers and other users of SD media have another concern - reliability.

What is Industrial Grade eMMC?

eMMC has seen strong adoption and become the storage of choice for consumer devices such as smartphones, e-readers and tablets. These small devices all run on battery power and require high-density storage with low power consumption -- at a low cost.

Automotive Challenges -- Security, Mount Times & Updates

Automobiles and Trucks have gone from simple contraptions to full blown multi-processor networks in just the last few years. Between M2M and the Internet of Things, today's vehicles are communicating more than ever. Here are some of the challenges we have observed in this industry.

Wish Granted

OEM customers have told us for years that struggles with NAND supply and lack of standards costs them a great deal of time and money. A shortage or EOL on a key component like NAND flash memory can cause product delivery delays that impact topline revenue and potentially company reputation. What they wish for is a "plug and play" option that lets them multi-source their flash memory.

Software Power Consumption

One of the questions we received at Datalight is whether our software affects the power consumption of embedded devices. Not being power experts ourselves, we found an intern and faculty advisor from our nearby University of Washington to help us out with the process.
