That's a good question.
In your computer there are two kinds of memory. The hard drive is non-volatile, which means when the power goes off the data is still there, encoded in the physical structure of the memory. The RAM chips are volatile, which means when the power goes out anything in the RAM chips is lost.
So is the brain volatile or non-volatile memory? If the power goes out are memories lost or are they retained in the physical structure of the brain? If brain memory is non-volatile the guy's brain could still be hacked after he was dead.
