Time will tell. The hype over the future of NAND technology, worth the fuss? NAND is non-volatile memory we use in today’s cameras and other flash media devices. It’s also used in a fast growing number of computers as a hard drive. What’s the meaning of non-volatile? It means the device will perform memory retention inside the NAND flash card even when the power is off. Power failures or logical corruption can lead to the need for flash memory recovery solutions.
NAND memory technology is getting smaller and smaller. Its capacity to hold memory and its long life have given this technology a boost. We use this technology in two ways. There is SLC and MLC flash. Both are initials for single and multi level cells. The technology spreads the memory out over the cells in an even distribution. The distribution of memory allows for better performance and faster read write cycles. Flash media powers the devices that we use everyday. Have a broken storage device?

NAND Flash Technology Uses Efficiency To Lower Market Price.
Flash technology, which got its name from the speed in which it works comes in two forms. NOR is the more sure footed type that quickly records memory sequentially. NAND on the other hand is a much more affordable sequential reader and writer of memory. NAND flash chips can store more data on less space by spreading it out, over sequential cells. Spreading out the data makes it better suited in the storage of mass data than NOR. NAND has rewritten the price rules. It’s much more affordable with its multi level cell upgrade.
Flash Memory Lifetime, what About Endurance?
How fast will these read, write and erase? How long will my device work before it breaks? How often can a person erase the rewritable cells in NAND Flash? The manufactures say, if used daily, that the average lifetime is between 10,000 erase and rewrites cycles. Other experts believe this number is lower. The makers of flash based memory chip are estimating users actually erase and rewrite less often. Is the average user only using a quarter to half the memory at a time? Are users filling the flash card to capacity? Manufacturers argue, the even distribution makes it a mute point.
Understanding NAND Flash. First Understand how Components Operate.
- The need for flash memory recovery results from defects in logical or hardware failure.
- A bit is a basic unit of information.
- It takes eight regular bits to make a single byte.
- Each single cell consists of transistor memory.
- In order to read and understand the information on a bit, it must have a logical method to define it.
- There are two and only two things that the bit understands, the numbers o, and 1.
- Single Level Cells only hold a single bit (SLC – NAND Flash). This being the old school design of what makes NAND. It’s costly to use the old “one-bit to one-cell” method of storing and reading memory.
- NAND is a logic-gate technology. This means it is the DNA of digital circuits. It is only logical that it can read the bit by answering its presentation of zero, with a one.
- As a single level cell, NAND Flash is as efficient as it can ever be. The technology has improved with MLC NAND Flash or multi level cells.
Multi Level Cells Hold More Bits.
In MLC NAND Flash, cells hold 2, 3, and 4 bits of information. This multi level cell flash increased efficiency, ensuing price drops. NAND Flash technology is used in Solid State Drives instead of traditional hard drives or standard hard discs. SSD technology is moving forward as it has no moving parts. SSDs can be used in a variety of devices. Solid state drives absorb shock and outdo traditional hard disks with moving parts. Moving parts on HDDs break easily. Recovery from flash memory devices is successful with SSD drives and any type of flash storage devices.
Flash Memory Talks the Talk But Can it Walk the Walk?
For a while there were companies coming out with new ideas of what NAND is and where this flash memory technology was heading. All this hype is beginning to fade in 2015. The new whispers are of PCM (Phase Change memory), MRAM (Magneto resistive RAM) and RRAM (Resistive RAM). Has SLC and MLC NAND Flash technology seen its day in the sun? No, not by a long shot, they can talk all they want about new technology. As long as we have NAND Flash we have a winner. NAND Flash Technology will be around for another ten years.
