There’s little advantage to supporting sizes between 2 n and 2 n For example, plugging an SD card labeled as ” MB” into my Linux box produces the following message:. 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. When the PC writes a logical sector, the page holding data for that sector will not be immediately erased.

While the latter may be very well datashewt by minimizing overhead of addressing, the former is puzzling for me. Sign up or log in Sign up using Google. All units are in um 3.

NC stands for No Connection. 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 datashret. Tray Packing for Chip A 2-inch square waffle style carrier for die with separate compartments for each die.

Although manufacturers recommended using part of the space for ECC, the primary purpose of the space was to facilitate block remapping. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.


Data for the WD Caviar Blue drive, but other manufacturers will handle more or less the same numbers: Dztasheet up using Facebook. Each pack has typically 25 wafers and then datasyeet packs are put into larger box depending on amounts of wafers. 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.

Each tray has a cavity size selected for the device that allows for easy loading and unloading and prevents rotation. Sign up using Email and Password. Refer to the bond pad location and identification table for a complete list of bond pads and X, Y coordinates.

I have never seen any flash chips with capacity not confined to the strict i.

Email Required, but never shown. 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? Sorry, but this is simply wrong. Test patterns, timing, voltage margins, limits, and test sequence are determined by individual product yields and reliability data. The chip you’ve shown is pretty standard compared to what I’ve seen: If you buy a 1TB hard disk and it appears to hold 1 MB, technically you’re not swindled, even when you actually did mean and expected 1 MiB.


I don’t consider it as “extra” or something because: Row 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. I didn’t say it’s not standard, but it is not a power of two. 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.

I’m curious to look at the datasheet The pack consists of clean paper to wrap the wafer, high cushioned sponge between wafer and hardly fragile plastic box with sponge. Further, in the rush to increase capacity some reliability is exchanged, but fixed with error detection. I don’t consider it as “extra” or something because:.

But I’ve also seen SPI-interface flashes where the actual native block size was not a power of two, k9g8g08u0aa actually a bit larger – for example, the AT45DBD has pages that you can set as being either or bytes long.
