    Hi,
    Well, it is possible only with devices which have built-in bootloader flash API (for example, Atmel Temics-formed devices such as (A)T89C51RB2/ RC2/ RD2/ ED2/ ID2/ AC2/ IC2/ CC01 etc). Such devices contain extra program called bootloader which provides in-system programming of device. Thanks for manufacturer, they install user API as well there. So, yes, it is possible to write program flash; read flash API/bootloader sources to understand how.
    Good days!
