There’s little advantage to supporting sizes between 2 n and 2 n I wonder what prevents manufacturers from creating such chips: Second, the NAND Flash have a standardized interface where interaction with external controller is done through a 8-bit bidirectional bus.

NAND Flash > MLC-large Block

Yes, ECC has been around for a long, long time, and thus flash manufacturers do support it. So the silicon usage efficiency is best at 2 n.

Can you provide a few examples? Please refer to the packaged product data sheet for functional and parametric datasjeet. I believe I did provide an example.

However with newer 3 bit per cell MLC flash the cost difference isn’t as great, and the need for error correction is greater. The chip you’ve shown is pretty standard compared to what I’ve dataeheet When k9g8g08u0z PC writes a logical sector, the page holding data for that sector will not be immediately erased.

Post as a guest Name. Some other topologies, such as 3D stacking, also result in odd factors. The count of pages and blocks in entire flash is still power of 2, and moreover, amount of bytes in data and OOB areas of page on their own is power of 2, too.

Is flash chip capacity really limited to the powers of 2? It may or may not be a coincidence; but in the question, I ask about flash chips, not flash cards. If it had, for example, pages, then it would be the one I’m searching for. The chip carriers will be labeled with the following information: I’ve came to this thought after examining some flash drives: If you need to create a device with memory in the range 2 n and 2 n-1 then you will generally find that buying the 2 n part is more cost effective than buying the 2 n-1 part and a smaller part.

I’ve updated the question with an example. By using our site, you acknowledge that you have read and understand our Cookie K9g808u0aPrivacy Policyand our Terms of Service.

Jar Packing for Datasjeet Jar Packing is made by Samsung Electronics and used by many customers that we deliver the requested datxsheet as wafer.

I didn’t say it’s not standard, but it is not a power of two. Sometimes – as with those packaged in USB or SD devices it’s easy to assume that the controller you access the memory through is reserving space to map out bad blocks, etc. Referenced to the center of each pad from the corner of left bottom.

Yes, they could make one, but it wouldn’t increase their bottom line. The pack consists of clean paper to wrap the wafer, high cushioned sponge between wafer and hardly fragile plastic box with sponge. This interface is not strictly serial, as there are 8 parallel lines of data, but it’s not parallel, too, as you cannot set up all the address on just that 8 pins.

Many of them, however, do this because they simply have too many bits due to their 3 bit per cell MLC flash. Data for the WD Caviar Blue drive, but other manufacturers will handle more or less the same numbers: We already have RAS and CAS, with one’s address space bigger than other, and the matrix is already asymmetrical — why do it exactly in the power of 2?


Oh, I’m very sorry, my comment should have been much better 3AM, you know So, what prevents a vendor from adding a bit more rows or columns? SAMSUNG reserves the right to change the probe program at any time to improve the reliability, packaged device yield, or performance of the product. Further, if you intend to put several of them together in a parallel access scheme, you will end up with gaps if each chip doesn’t address 2 n.

I don’t think so. They are typically more expensive than the byte block size parts, though, which again points to cost efficiency of silicon being the reason most flash favors power of two.

If memory chips used logical pages of bytes each rather thandrives would have to store a page worth of bookkeeping information beside each page of data–a massive waste.

Tray Packing for Chip A 2-inch square waffle style carrier for die with separate compartments for each die. For example, plugging an SD card labeled as ” MB” into my Linux box produces the following message: The factorization of the number of sectors shows that there’s kg8g08u0a logic in it, the numbers are chosen to give a round number in GB, not GiB. But the capacity of mass storage device is less than that of the flash because of spare blocks which will be used in place of bad blocks, which are present on any new MLC NAND device and are appearing through its life.
