It is a type of EEPROM that is much faster than traditional EEPROM. It reads or writes data in form of blocks. Block size is usually 512 bytes.
Sometimes flash memory is termed as flash RAM. But there is a much difference between flash RAM and flash memory. Flash RAM requires constant power to maintain its contents whereas flash ROM can store its contents even without any power.
Inside Flash Chips
Boot Block Section: - This area is used for booting and may consist of one or more blocks that is kept secure from erasing blocks. This block is generally used to store firmware of for memory management.
Block Erase Section: -It is the user working area and is divided into blocks. This area can be accessed randomly for read/write operations. Memory Erased blocks contain no data.
