I know, they are technically the same, but from what I read, NAND flash chips can be controlled better like putting it into standby and waking it up in the matter of a few nanoseconds, which could be useful for recording projects that need to transfer the RAM buffer every few seconds.
I would need at least 128GB / 1TBit, so NOR flash chips are unfortunately not an option.
It would be worth it to implement a BGA package, but only if that saves more power than a micro SD card which is typically designed to be as fast as possible for the end consumer.
Also, I was not able to find out much about that, but I read that NAND flash chips have two modes: SD and SPI. Does that mean they can be connected just like a micro SD card via SPI protocol to a MCU just with the addition of more pins like chip enable, etc.?
Unfortunately, it is pretty hard to find any datasheets of bigger NAND flash chips, so maybe some people with experience on that matter can help. :)
And besides all of this, is there any other method to save data more efficiently on battery powered devices?
