Wear leveling will help to reduce the wearing out of blocksover the mapping rules. The FTL provides the mapping rules from logical to physical addressing. FTL AND WEAR LEVELING Wear leveling is implemented in the flash translation layer (FTL), which is the inter-medium mechanism between the file system and the NANDflash device. This method is called wear leveling.There are two primary wear leveling mechanisms embedded in the flash translation layer (FTL) – static and dynamic. To accomplish this, one method is to manage the P/E cycleof each block individually, which will help to regularly distribute them and avoid overlaying on some blocks. Therefore, efficient management of wearin whole blocks is required in order to maximize the lifespan of a NAND flash device. The key solution for this constraint is tomanage the attrition rate in the entire NAND flash device so that each block will be evenly distributed. INTRODUCTION For today’s NAND flash devices, the main limitation is Program/Erase lifespan (number of P/E cycles).

So, that’s really all I have to say for this month and I really can’t believe the first three months of 2014 has already come and gone but no matter as they year seems to be a very interesting one. hi, i bought a i flash usb drive from lowyat last week for my i phone. Finally, we also have a very good selection of products when it comes to our reviews and although we were a little strapped for time, we still soldiered on to bring you our thoughts on some of the latest gadgets and hardware. Of course, that isn’t all we have in store for you this month as we other features that are also very informative like the Repair Special that is catered to all you DIY-junkies out there and also an article that tells you how to stop Google and Facebook using your name and photo for advertisements and so much more. In our cover story, we find out how the methods hackers used to find loopholes, what they are used for, how much they cost and what are some of the consequences it can bring to individuals and an entire nation. This month, our cover story is about security loopholes and how it has become quite a commodity in the industry as software engineers, government officials and even cybercriminals fight for it for their own personal gains. But let’s set our focus back to this issue. There were loads of impressive new devices showcased at the event and we can’t wait to share them with you. Other than those events, the Mobile World Congress also took place in February but it was way too close to our closing period so we have kept the highlights of that show for next month. Be sure to check out all our coverage for the NVIDIA, Samsung and OKI inside. February really blazed by us as Nazrin and myself found ourselves going for three different work trips in Vietnam, Indonesia and Japan. S the first quarter of the year is about to come to a close, I have to say that it really has been a very exciting few months thanks the numerous events we have had here locally and overseas.
