To rewrite the old memory means to destroy the previous structure of synapses that hold the old memory and build the new structure of synapses to hold the new memory. The brain will end up having the same amount of memory but wasting its resource to do that.

Can the human brain run out of memory?
When our brains are overloaded the same neurones are used in multiple memories in very flexible ways. So we might become more likely to confuse events, or have other difficulties in remembering, but we can’t really say that we ‘run out of memory’.

How many years of memory can the brain hold?
A rough calculation by Paul Reber, Professor of Psychology at Northwestern University suggests that the brain can store 2.5 PETABYTES of data – that’s 2,500,000 Gigabytes, or 300 years worth of TV. So if we have a virtually unlimited storage capacity, why do we still forget so much?
How much knowledge can the brain hold?
2.5 million gigabytes
As a number, a “petabyte” means 1024 terabytes or a million gigabytes, so the average adult human brain has the ability to store the equivalent of 2.5 million gigabytes digital memory.
Is the human brain infinite?
Yes, memory depends on forming new neural connections, and the brain has an infinite number of neurons and a limited space in which to add more connections between them.
Can your brain get full?
No, the brain can’t get full. The brain is so specialized that it discards unnecessary information to make more room for new memories. Many times, when we study for too long, it seems that our brain can no longer hold more information.
How important is the human memory?
Memory has a fundamental role in life, reflecting the past as the past, and offering the possibility of reusing all past and present experiences, as well as helping to ensure continuity between what was and what was going to be.
Can the brain store unlimited information?
The amount of information the brain can store in its many trillions of synapses is not infinite, but it is large enough that the amount we can learn is not limited by the brain’s storage capacity. However, there are other factors that do limit how much we can learn. The first is our limited attention.
Why do we forget?
So, in effect, the scientists believe we learn to forget some memories while retaining others that are important. Forgetting of course comes at the cost of lost information, but a growing body of research indicates that, at least in some cases, forgetting is due to altered memory access rather than memory loss.
How powerful is the human brain?
The human brain can generate about 23 watts of power (enough to power a lightbulb). All that power calls for some much-needed rest. Adequate sleep helps maintain the pathways in your brain.
How much do we forget in 24 hours?
70%
Some studies suggest that humans forget approx 50% of new information within an hour of learning it. That goes up to an average of 70% within 24 hours.
Do you have amnesia?
Symptoms of amnesia
The primary symptom of amnesia is memory loss or the inability to form new memories. If you have amnesia, you may experience the following: difficulty recalling facts, events, places, or specific details (which can range from what you ate this morning to the name of the current president)
Why students forget what they learn?
The most common reason why students forget is because the material is under learned. To remember something, it must first be learned, that is, stored in long-term memory. If you don’t do what is necessary to get information into your long-term memory, you have under learned the material and forgetting is normal.
How can I learn to not forget?
