Firstly, the fabrication process everyone is excited about puts the memrister cells directly atop the cmos logic gates as just another layer to the die. No external memory bus to tap into. So you'd need the sort of equipment used to remove layers from dies to expose the cells for reverse engineering, testing, etc. If someone with these resources is after you, you're already fucked regardless of the exact technological vector.
Secondly, a system designer could trivially add some amount of volatile storage for holding security sensitive data. Various schemes of encrypted pages that are decrypted using a key stored in volatile SRM within the CMS could be used. In other words, we could do the same things we currently do with hard drives between the memrister array and SRAM that acts as a decrypted cache.
Thirdly, you're applying an expectation to all memristers that is not applied to existing storage technologies. It might be a fair criticism of a concrete product that operates in an insecure way, but it's absurd to apply this expectation to an entire technology.

I disagree.
