iPhones are fully encrypted, the encryption key being generated and stored when you first configure the device, then as you add things to the phone they’re stored encrypted.
When you “wipe” an iPhone, you don’t wipe the memory, you wipe the encryption key which almost instantly makes it near impossible to recover any of the memory contents. So even if you could remove the chips you couldn’t read the content, and there’s no way to recover the encryption key.
