    1. A key disadvantage of flash memory is that it can endure only a relatively small number of write cycles in a specific block.

      disadvantage of Flash memory

    1. Basically, flash generally is erased in blocks of ~64-512 kilobytes. Therefore, for every write anywhere within that block, the controller has to erase the entire block, using a write cycle for the entire block.

      Flash is written in block level, every block size is fixed

    2. To be pedantic, FLASH memory is merely a form of EEPROM: There is a marketing / branding aspect here. Typically, the distinction used today is that EEPROMS are single-byte (or storage word) erasable / rewritable, while FLASH is block-based for erase/write operations.

      Diffs between Flash and EEPROM. Flash write is block based while EEPROM is single byte based.
