WebOct 23, 2024 · A sector is the minimal unit of space you can write and read to a hard drive. A cluster is the minimal unit of space for management of the space within a file system. Most file systems seem to use clusters, ReiserFS is a rare exception as far as I know. Every sector can only belong to one cluster.
Web• Smallest erasable block size is called Sector –May be 4/32/64/256 KB • Sectors sub-divided into Pages –May be 256/512 bytes –Flash program is usually in page size chunks (though not necessary) • Need to send Write Enable(WREN) command before a write or erase operation • Most flashes support Read ID(RDID) command for flash detection 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.
