``am asking about the way EDIG refers to flash memory as primary memory. They also mention that the Micro OS is for devices that use removable flash memory, I thought that you would be able to explain what they mean in their statements. That`s why I asked for a layman`s explanation.

1. MOS can emulate primary(main memory)...they remove RAM(random access memory) normally associated with flash management and through a small cache matched to the read/write block of the flash...manipulate data within...and can be placed in a stand alone embedded condition....

2 ``They also mention that the Micro OS is for devices that use removable flash memory``

That is correct...see my previous post for this info....they can create a controller of their IP for a removable flash as a subordinate.
