Use this option to control how much extra memory is used
by the FLASH drivers to perform certain operations. This
memory is used to hold driver functions in RAM (for platforms
which require it). The value should thus be large enough
to hold any such driver. Reducing this value will make
more RAM available to general programs."

This option makes the IO driver copy the device
