When writing our software, we need to think about hardware which will run our software.

Quote:
Whenever a developer is using something named 'X Emulation over Y', she may expect that a faithful emulation exhibits the same properties as original (non-emulated) X.

You cannot erase single byte of Flash, but need to erase the whole page
Another Quote:
First of all, we want to be sure that whatever-is-already-written to our persistent storage, stays there; this property is known as Durability.

Abstract:
Definition of "Modified Harvard" architecture is confusing and overbroad. Proposed alternatives are "Almost-Harvard" and "Almost-von-Neumann
