Flash block vs sector
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. WebBlock devices had a fixed size and could be seek-ed. They also happened to be organized in blocks of multiple bytes, usually 512. Flash doesn't match the description of either block or character devices. They behave similar to block device, but have differences. For example, block devices don't distinguish between write and erase operations.

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. WebSectors are the smallest logical unit a hard drive cares about, it used to 512b, but most modern drives use 4096b. By "cares about", I mean it contains a header, the actual data, …
