Can you provide a few examples? The factorization of the number of sectors shows that there’s no logic in it, the numbers are chosen to give a round number in GB, not GiB. The chip you’ve shown is pretty standard compared to what I’ve seen: When the PC writes a logical sector, the page holding data for that sector will not k9g8b08u0a immediately erased. In these cases the best efficiency comes down again to addressing according to the flash topology. 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.

So the silicon usage efficiency is best datashdet 2 n.
The pack consists 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. There is no practical reason that couldn’t be done. Sign up using Email and Password. There’s little advantage to supporting sizes between 2 n and 2 n I’ve updated the question with an example. datasueet
But yes, not all flash is power of two. All units are in um 3. The error-correction logic doesn’t count in either number.
Each pack has typically 25 wafers and then several packs are put into larger box depending on amounts of wafers. Further, in the rush to increase capacity some reliability is exchanged, but fixed with error detection. However with newer 3 bit per cell MLC flash the cost difference isn’t as great, and the need for error correction is greater. I believe I did provide an example. But I’ve also seen SPI-interface flashes where the actual native block size was not a power of two, but actually a bit larger – for example, the AT45DBD has pages that you can daasheet as being either or bytes long.
I wonder what prevents manufacturers from creating such chips: They aren’t uncommon, but they are really only used when robust error correction and detection is required.

Post as a guest Name. I don’t consider it as “extra” or something because:. Although manufacturers recommended using part of the space for ECC, the primary purpose of the datasueet was to facilitate block remapping.
Refer to the bond pad location and identification table for a complete list of bond pads and X, Y coordinates. Second, the NAND Flash have a standardized interface where interaction with external controller is done through a 8-bit bidirectional bus.
For example, plugging an SD card labeled as ” MB” into my Linux box produces the following message:. I’ve came to this thought after examining some flash drives: If you need dstasheet create a device with memory in the range 2 n and ,9g8g08u0a 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 don’t consider it as “extra” or something because: NC stands for No Connection. It is almost always used to store the ECC codes and not the actual data; hence, the amount of information is same with or without OOB. For example, plugging an SD card labeled as ” MB” into my Linux box produces the following message: The chip carriers will be labeled with the following information: Dxtasheet and column addresses already exceed the bus width, and several transfer cycles are used to select a block; they do not fill all 16 bits as well, so there is already some extra space.
Further, dataeheet 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. Sometimes – as with those k9g808u0a 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.
Yes, they could make one, but it wouldn’t increase their bottom line.
