    HELLO,
    I HAVE SPI FLASH MEMORY MX25L12845E , IWANT TOCOPY THE DATA OF THIS MEMORY TO ANOTHER MX25L12845E. HOW DO IDO IT.
    Is there any programmer which can retrieve the data from memory and then write it to another memory.?

    Something like a Bus Pirate should handle the physical layer(electrical signals) as it can work an SPI bus.

    But you still need to provide a protocol level meaning some program that respects what the data means, that knows where to poke and where to peek.

    These things tend to be custom builds. I doubt you will find something on someone's shelf.

    There are programmers which of course can read a serial FLASH and write the dump to another chip.

    Finding one supporting OPs chip might not be cheap.

    I use my GAL programmer to write serial FLASH, but it can easily be done with a USB PIC, or such a evalution board. You could work it into a FLASH writer if you wanted to.
