The ROM (Read Only Memory) of the system is used for multiple purposes. First there is a section to perform a basic loader of the kernel and allow access to the ram and ROM portion of the storage. So some programs are stored in ROM and executed in ROM. This is known as Execute In Place (XIP). Also, the ROM is compressed so the OEM can maximize the amount of programs and data that is stored there. The newer devices uses flash memory for the ROM so they can be upgraded. The current upgrade process requires the user to install a full set of the whole ROM onto the device. It does not allow the user to upgrade selected files in the system. Also, if there is (a need for a patch, the OEM can install an updated file in RAM and it will logically replace the ROM file when required.
