WebPage is the smallest data unit that the VM manages. Block is a sequence of bits and bytes. Block is made up of sectors. A page is made up of unit blocks or groups of blocks. A block is made up of either one sector or many sectors (2, 4, 6...), which means blocks have varied in sizes. Pages have a fixed size. WebOn a spinning disk, a sector is the minimum unit of transfer in both directions, both reading and writing. On flash memory, however, the minimum size of a read is typically much smaller than a minimum write. In essence, the sectors are numbered 0, 1, 2, etc. up to (N-1), where N is the number of sectors on the disk.

WebMay 30, 2016 · This allows for the design of stored block type data in the FRAM chip to be buffered in RAM and then only needing to update specific bytes that have changed as opposed to whole blocks like in Flash. This performance improvement alone can make the serial nature of a SPI or I 2 C interfaced FRAM chip not bog down an application.
WebIn my experience, all of the older flash chips allow you to change any 1 bit to a 0 bit without an erase cycle, even if that bit is in a page or even a byte that has already had other bits programmed to zero -- a page of flash can be programmed multiple times between erases. (This is called "multiple-write" in the YAFFS article).
