ATJ209* Series Datasheets
 

I've re-read the ATJ2085* series datasheets and have found that in actual fact, the ATJ2085 is able to support upto 4GigaBytes of flash memory (ie 2x2GB), as contrary to the belief that it can only support a maximum of 2GB. Some boards on some players even had an extra slot for another memory chip, possibly for two 2GB chips to form 4GB.

As such, would like to ask if anyone had come across or have a copy of the ATJ209* series datasheets. So that the maximum 4GB support can be further verified. As there were a very small number of people in the past who claimed that they had 4GB even after formatting with Disk Tool.
