A phone's 128MB memory is not same as PC's 128MB. Phones usually have execute in place (XIP) memories, which means the OS and apps share some space. Also each app is budgeted a certain memory (Phones use near real time OSs compared to usual OSs in PCs), so as not to exceed the memory limit anytime. There is no virtual memory to grow to. So the assumption is not correct especially for feature phones that do not use modern smart phone OSs which are more nearer (by no means same) to desktop counterparts.
