title: Replay Protected Memory Block - eMMC
body: <p>I'm a beginner. I was reading about <code>Replay Protected Memory Block</code> in <code>eMMC</code> and understood about its main purpose. It is a specific memory area which is in an authenticated and replay protected manner. But, I'd like to know practically what kind of data requires that kind of memory area, with respect to embedded devices. Whether the booting related configurations? or read-only registers? or anything else?</p>
