With all due respect, your use of "bidimensionality" is nonsense. You
claim to use it to refer to the physical level of discourse but then you
use it when referring directly to logical entities.
You claim that physical memories are multidimensional; however, on the
one occasion I recall anyone using a computational model with multiple
dimensions of memories, it was used in the constructive proof that a
single-tape turing machine is just as expressive as a multiple-tape
Segmented memory is not the same as two-dimensional memory.
Virtual memory is not the same as two-dimensional memory.

Segmented memory is not the same as two-dimensional memory. Virtual memory is not the same as two-dimensional memory.Paged memory is not the same as two-dimensional memory.
In the computational models people will find familiar, memory uses a linear address space: it has one dimension generally expressed as an unsigned integer defined in some large range. That property is a property of the physical address space and not a property of the data stored in the memory.
If you plan to use an unfamiliar computational model, you will have to fully define that computational model or nobody will have a clue what you are talking about.
To give yourself some indication of why anglophones cannot understand you when you use the word "bidimensionality" while flitting between the logical and the physical, I suggest you search for the following terms on google including the quotation marks for each.
"virtual memory" "segmented memory" "linear memory" "bidimensional memory"
While I get tens of thousands of hits or more for the first two, I get a total of 4 hits for the last one. Two of those hits relate to psychology. One of those hits defines a computational model for the study of evolution. The remaining hit, which is only available in the cache, appears in the description of a speech given once about a year ago on a topic of digital image processing related to cryptography.

If you want to use a computational model using a non-linear address space, you will have to fully define the computational model.

J M Davitt asked once for clarification indicating you were not communicating well and once pointed out that your style of quoting interferes with communication. I don't recall him expressing any confidence in his comprehension of what you wrote.
I long ago added Alvin to my twit-filter. I forget whether that was due
to a lack of intellectual honesty on his part or worse. That he might
pretend to make sense of what you wrote does not make it any more sensible.

You have not established that anyone really made sense of what you wrote. One person tried to rephrase what you wrote into something heconsidered sensible, and he asked you for clarification at that time. The other person is just a fool. Fools talk nonsense all the time.

Nothing is really relevant to nonsense. I am trying to give you an opportunity to rephrase what you are trying to communicate into something sensible. You keep refusing and insisting that your prior gibberish should make sense to people. Clearly, it does not.

I disagree. Confusing a property of a physical address space with a
property of a logical entity is nonsense. When I put a potato into
boiling water, I don't conclude that the boiling point of potatos is 100
degrees celsius nor do I conclude it is a property of cooked potatos as
opposed to potatos in general.
Yet, having put a logical structure into a linear memory, you expressed
a property of the linear memory as a property of the logical structure.
Don't do that. It's nonsense even if you say it only applies to the
implementation of the logical structure in the physical address space.

You and I obviously use different definitions for "clearly". You clearly and repeatedly used "bidimensionality" in reference to an SQL table.
You even indicated rightfully to vc

I simply repeated your claim, and I am trying to give you the benefit of the doubt. Thus far, I have assumed the problems with communication stemmed from your use of a foreign language, and I am trying to give you the opportunity to overcome that impediment.
What you believe is

It wasn't a yes or no question. You seem to be claiming that I asked a loaded question; however, I think most of the knowledgeable english speaking people will find the question very reasonable given your previous statements.
Are you saying you want to rephrase what you wrote previously such that you no longer express the properties of the physical memory as properties of the logical entity?

I am not sure why you think that. I suggest you consider: http://en.wikipedia.org/wiki/Turing_machine#Multi-tape_machines
I likewise suggest you consider that the various classes of automata can
accept the same languages:

I am not sure how else you want me to express that something you write makes no sense. While I understand it will require much more work from you to discover or look up the correct english word for what you are trying to communicate, making up gibberish wastes time while defeating your purpose.
