1.4 Memory on the Braille Sense U2 QWERTY
The Braille Sense U2 QWERTY has 256MB of RAM (random access
memory) and 32GB of flash memory. The RAM is memory reserved for
running programs. RAM is a temporary storage area for any program files
that are running or any currently open documents. The data in the RAM
area disappears if your battery depletes, and the AC adapter is not
connected. The RAM data also disappears when Braille Sense U2
QWERTY reboots for any reason. This means, if you have an open
document which you have not saved, the unsaved data disappears.
