I would like to add to Vladislav Povyshev's answer that human memory can change greatly over time under the influence of external factors of any nature. That is, for example, you remember that many years ago your girlfriend did not come to your holiday because her younger brother fell ill with chickenpox, and as a result she was not allowed to visit you. In fact, this girlfriend came, and you messed up everything, because it happened a few years later, but not at your party, but at your sister's party, and you worried about her so much that over time, your brain has already twisted everything and gave out this "memory".
On this topic, you can watch the series Adam spoils everything (episode 4). What's good about it is that all the facts that are said in the series are confirmed by more than one scientific work or research.
Ie a mechanism that will allow you to get some kind of "direct" access to memory?
Apparently not, because it is already obvious that human memory is arranged fundamentally differently than "computer". Computer memory stores, in a certain sense, a snapshot of a state, a structured, unambiguously interpreted set of information. Human memory is a set of associations, a set of sensations and perceptions so complex that a person cannot explain his own memories.
Breathing in the aroma of fresh bread, you remember a trip to the bakery in third grade and a classmate's bow, white, because she had her birthday, March 26, just tomorrow, and we must not forget to buy white lilies, they are so loves your wife, who was a girl with a white bow, and who has a birthday tomorrow.
