A possible memory scheme and most likely will be holographic data storage which is a crystal the size of a sugar cube that can hold over a terabyte of date. Memory is allocated to the flash memory via the flash memory controller (or flash controller) to simplify it.

Apossible memory scheme that could take place is PCM Phase Change Memory and could likely take the place of flash memory.

Great link Jason, is that the link I was showing in class? Hmmm, but yeah I do believe holographic memory and storage are in the near future, but the size of the application is still impractical for commercial use.

Flash memory uses memory cells from floating gate transistors in single level or multi level devices, by applying a charge to these devices it creates a memory blocks.

Among future memory schemes, phase-change memory is a type of non-volatile computer memory. Utilizing heat application produced by the passage on an electric current, the product can be "switched" between two states, crystalline and amorphous.
A way memory can be allocated on flash memory computers with the process of Microsoft Terminal Server included in Microsoft Windows Server 2003. You can allocate a fixed memory usage for every user from the Terminal Services Configuration application.

Flash memory is shock resistance. flash memory has been adopted by personal computers and servers in the form of onboard cache and solid-state disk .There are two types of flash memories: NOR and NAND flash memories Flash memory can't be overwritten. I believe that what makes it a promblem.,

According to Sciencedaily.com, the problem with flash memory is that with the pursuit of faster performance and greater storage capacity, the floating gate structure will continue to shrink and flash memory will be degraded and lose its ability to retain its memory.

possible memory scheme and most likely will be holographic data storage, PCM Phase Change Memory, are possible replacements for flash memory.

one possible memory scheme that is already kind of taking affect are SSD's which are non moving hard drives that store memory through electrical charges.
anothe possible scheme is holographic storage which can hold up to 1 TB per disk. this method reaches deep in the layers of the disk and reacts alot different to light...

Holographic information memory systems would seem to me to be the way forward. Today’s mechanical systems retrieve data in a serial manner one bit at a time but holographic systems will retrieve data a page at a time up to a million bits at a time. Vast improvements in speed will be achieved because since light shifting is far quicker and more efficient than mechanical systems.

Transactional memory is a possible memory scheme. It's much harder to get a deadlock (still possible) and it doesn’t suffer from the granularity problem.

Molecular memory is still in the realm of research, with scientists testing various ways to make a practical product that can be introduced in the market. In this, individual molecules and nano-wires are used to create large arrays of memory bits. Each molecule acts like a switch that can be either in the off or on state, thus representing digital data.
With this technology, up to 50 times more data can be crammed into the same storage space as today's magnetic storage devices such as hard disks. Nano technology-based devices that may replace today's silicon storage media are still a couple of decades away.

Transactional memory is not a technology or a term most mainstream developers are familiar with today. However, it appears to be the key to unlocking the full potential of next-generation chip multiprocessing technology; accelerating both performance and adoption. The advent of multi-core processors has renewed interest in the idea of incorporating transactions into the programming model used to write parallel programs. This approach offers an alternative, and hopefully better, way to coordinate concurrent threads.

In a future ruled by man ruled by machines ruled by man, there will multiple integrated forms of memory. I think breakthroughs in biochemistry will bring rise to date being stored within the human DNA strand itself. This, in turn will be simultaneously backed up onto a remote quantum storage device via a neural quantum entanglement device. the backup process will be facilitated by nanomachines in the body xor "smart" prosthesis. People will simply use terminals to access the data stored within themselves.
PMC(Programmable metallization cell) is a possible memory scheme of the future. It uses a technique of manipulating charged particles at a molecular scale. It is supposedly one-tenth of the cost of flash memory while 1000 times as energy efficient.

Reading into DNA memory, capacity is a massive advantage, rather than working on a level of small switches, the possibility of storing memory as base 8 RNA or even higher on a molecular level offers massive storage capacities. A method of flash memory allocation is simply by the Flash memory controller, or in more expedient cases a third party allocation software suite.

I agree that holographic memory schemes are definitely on the horizon of becoming a reality. According to PCMag.com, IBM reported that holographs are the number one technology idea of becoming a reality within the next five years.

Flash memory is used for easy and fast information storage and is known as solid state storage as it has no moving parts. It uses tunneling to alter the placement of electrons.
