    FRAM with DDR interface

    Hi all,
    I am new to forum. Sorry If my question is repeated.

    Is any FRAM is available with DDR interface? As far as my search, i found paraller interface and serial interface (I2C and SPI). Is it possible to design a DDR FRAM by using parallel interface FRAM?

    Please help me ....

    Re: FRAM with DDR interface

    You have to understand why DRAM chips operate at DDR in the first place...
    This because of the massive bandwidth they are capable to deliver on the silicon level.

    On the other hand (last time I checked) - FRAMs chips don't even come close to that bandwidth performance. So why solve a problem that doesn't exist ?
    The FRAM's internal transaction limitations will be a bottleneck long before the single data rate bandwidth is exhausted.
