1. A memory device comprising: (a) a RAM operative to provide run-time execution functionality to a host, the RAM defined on a first die; (b) a flash memory operative to store, for said host, code selected from the group consisting of an operating system, a pre-stored application, a downloaded application and user data, the flash memory defined on a second die, the flash memory capable of communicating directly with a host system using different signals that are distinct from signals communicated by the RAM; (c) an interface for communicating with said host using only a RAM protocol; and (d) a controller, of the flash memory, that is operative to exchange said code residing on the flash memory directly with said host using said RAM protocol independently of said RAM and without using said RAM, in support of said storing of said code, and that also is operative to exchange signals directly between said interface and said RAM in support of said run-time execution functionality, the controller fabricated on the first die alongside the RAM.
