        abstract = {Dual bank flash memory technology (often referred to as dual - work or simultaneous operation flash is a memory architecture that split the storage in to two independent section or BANK. it is primary purpose is to allow system to perform read-while-write (RWW)operation reading from one bank while concurrently programming or rising other .the physical flash array is dived e in to two distinct logical entities (eg BANK1 and BANK 2) each with its own base address standard single- bank flash memory usually stalls the CPU during a write or erase operation because it is cannot read code instruction from the same array it is modifying dual-bank technology eliminates this stall by isolating the operation  the simultaneously operation high-end micro controller like certain STM 32 series( software transactional memory) can execute program code in one bank while receiving and writing a firmware update in to the second bank. The firmware update OTA you can perform “IN_ APPLICATION PROGRAMMING” (IAP). without stopping system. The new firmware is written to the active bank  and are verified system “SWAP” the bank (often via configuration register) to boot from the new code system can continuously read application code from one bank to while logging high - frequency sensor data to the other ensuring the time critical operation are not integrated but long-flash -erase cycle by keep in the older version of firmware in the first bank while writing new version to the second. the system can easily revert to the utilize bank if update fails. in many implementations. the physical address of the logical bank can be swapped in hardware so that the new code always appear at the system primary boot address. dual bank mode is often optional and must be enabled through specific hardware “optional bytes” or register developer must manage the linker script carefully to ensure the application fit with the half with the total flash. if bank swapping is included or distributed libraries across both bank it max capability is needed in mobile communication used in devices like blue-tooth enabled phone and PDA s to allow rapid flash update while running real-time task.},
