    The address decode slots are 256MB, the 0x60000000 slot is subdivided into four 64MB sections.

    One could perhaps page in quite significant blocks of memory beyond the primary limitations. ​

    Hi Tesla,

    Thanks for reply,

    the FMC bus having address bus of 24 bits, by using which we can interface & access M29W256 (256 block memory)

    0693W00000QM1uwQAD.pngDoes it possible to access more memory space, either by changing block size or using M29W512 device on same address bus?
