HP Prime micro sd

[math7]

According to what Tim Wessman said when adding data and applications and programs in the HP Prime these data and programs are recorded inside the "256 MB" of flash memory, and every time the calculator is turned on the data is extracted from this Flash memory and loaded into the RAM of approximately 17MB. Is this so or am I wrong? Someone else understood that? Because if it were then the Prime would have a fairly large memory for hundreds of applications and programs, but I do not know if I understood this wrong or not.
