If we persume that life is completely based on the physical world, then yes consciousness is based on memory and you can somehow replicate the same consciousness which will continue with different experiences.

But if consciousness is based on what is percieved from physical world, then the consciousness can really take different forms, be parallel, be one single consciousness, and even not be dependant on time at all.

I think more interesting concept, than comparing death with being partially unconscious, is losing your complete memory. If consciousness is related on having past memories and experiences, how can we say a person can be conscious and function without having any single recollection of anything that ever happened.
