Memory extraction is likely impossible, as I expect that every brain encodes long-term memory slightly differently. There was a demonstration of partially decoding images from _surface memory_ that a subject was already thinking of, but that only works because they were reading off the visual cortex, which brains use to reconstruct scenes from long-term-memory and is better understood. [1]
That said, directly reading memories is unlikely to be necessary. In Daniel Suarez's Daemon/Freedom™, he proposes using fMRI and increasingly narrow questions to extract truthful information. The blood flow in our brains changes when we lie, and is much easier and faster to detect.
