what will be the maximum size of external parallel SRAM & NOR flash, that can be interfaced with STM32F429IIT6?

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)

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