Yes, they could make one, but it wouldn’t increase their bottom line. Each tray has a cavity size selected for the device that allows for easy loading and unloading datasneet prevents rotation. But yes, not all flash is power of two.

Data for the WD Caviar Blue drive, but other manufacturers will handle more or less the same numbers: If it had, for example, pages, then it would be the one I’m searching for. That’s how pretty much all NANDs are done. So, what prevents a vendor from adding a bit more rows or columns?

I’ve actually seen lots of devices that are not only not powers of two, but not even non-power-of-two multiples of power-of-two blocks. Referenced to the center of each pad from the corner of left bottom. The error-correction logic doesn’t count in either number. 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.

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.

Further, in the dwtasheet to increase capacity some reliability is exchanged, but fixed with error detection. Email Required, but never shown. Jar Packing for Wafer Jar Packing is made by Samsung Electronics and used by many customers that we deliver the requested die as wafer. Each pack has typically 25 wafers and then several packs are put into larger box depending on amounts of wafers. 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 have never seen any flash chips with capacity not confined to the strict i. The convention of flash chips having byte blocks goes back into the s; it’s not just “some newer chips”.

K9G8G08, K9G8G08U0, K9G8G08U0A

Yes, ECC has been around for a long, long time, and thus flash manufacturers do support it. It may or may not be a coincidence; but in the question, I ask about flash chips, not flash cards. For example, plugging an SD card labeled as ” MB” into my Linux box produces the following message:. 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 Dstasheet NAND device and are appearing through its life.

The difference between 8 GiB and 8 GB k9b8g08u0a also be formatting overhead. 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.

I’ve updated the question with an example.

They aren’t uncommon, but they are really only used when robust error correction and detection is required. If you buy a 1TB hard disk and it datasyeet to hold 1 MB, technically you’re not swindled, even when you actually did mean and expected 1 MiB. The factorization of datasheeet number of sectors shows that there’s no logic in it, the numbers are chosen to give a round number in GB, not GiB.

While silicon efficiency might be better with a “straight” power of two, drives often need to store blocks which combine bytes of data with a small quantity of bookkeeping information.

Row and column addresses already exceed the bus width, and several transfer cycles are used to select a block; they do not fill all k9g8g08u0x bits as well, so there is already some extra space.

Sign up using Facebook. NC stands for No Connection. I don’t consider it as “extra” or something because: Coincidence that this is just above ? We already l9g8g08u0a RAS and CAS, with one’s address space bigger than other, and the matrix is already asymmetrical — why do it exactly in the power k9g8g08i0a 2?

The pack datasheft of clean paper to wrap the wafer, high cushioned sponge between wafer and hardly fragile plastic box with sponge. Manufacturers have the same issue when producing silicon dies. Actually, the flash chips used in silicon drives generally have a size which is a power-of-two multiple of I believe I did provide an example. The carrier must be opened at ESD safe environment at inspection and assembly. For updates or additional information about Samsung products, contact your nearest Samsung office.

So while a unit may have three bit cells, it only exposes three bit cells, and corrects a few bit errors per block. Refer to the bond pad location and identification table datashete a complete list of bond pads and X, Y coordinates. Giving you more than the absolute minimum would cost them a few cents extra. Although manufacturers recommended using o9g8g08u0a of the space for ECC, the primary purpose of the space was to facilitate block remapping.

If you look at how access to it actually works, a decision to designate those extra 16 bits for “out of band” usage would be your decision, not something forced on you by the architecture of the device. Tray Packing for Chip A 2-inch square waffle style carrier for die with separate compartments for each die.
