Flash memory controller makers - who's out there

[jonnyyyl]

Hi all,

I'm trying to understand the occurring of the memory scene. I am very new to this but this stuff sounds quite fascinating.

 

I recently read several articles on it, and I'm trying to put together a coherent picture.

 

To my best understanding, Samsung, Sandisk, Toshiba, SK Hynix and Micron are pretty much the largest supplies of (not sure of correct terminology, NAND controllers or NAND memory?), with Samsung being top, followed by Toshiba and Sandisk, making up the top 3.

 

- my question here is what is the obvious differences in design/output/read/write among them, in layman terms?

 

Recent developments include the RRAM technology, which in short provides a highly improved benchmark results.

 

- Who's behind it?

- How do they compare to those PCI-e SSDs?

 

 

If I got something wrong on the concepts/etc, please do enlighten me.

Thanks guys!

good read
 

The SSD processor (or controller is it is more commonly referred to) is the heart and soul of the SSD.  It is the engine by which information is pulled from storage, translated and then sent to the SATA interface for travel to your computer system.  It is the sole reason that a typical SSD is 5-6 times faster than a hard drive in data travel and also the reason that we see a starting point of about a 90x increase in the information retrieval (disk access) from an SSD as compared to that of a hard drive.

 

Also Pcie ssd has a faster interface (80Gb/s) compared to Sata  which max at 6Gb/s

SSD´s is basicly a overgeared Ram put in a case, but here the bits is kept by permanet transistors, for these to be fast you need a voltage and a transitor, but the smaller you make them the harder it is to read and write becouse the narrow space for the voltage to flow, thus samsung made their Vram where they stack the memory in layeres and can make them bigger than before and make it easier for the voltage to flow, and giving better read and write time plus the lifespand is better too.

 

RRam is basicly a premium  SSD With memory stored in betweed atoms and not made up transistors from Si.

 

PCI-e SSD´s is a SSD put on an PCI board instead of SATA(the controller is often the same, fx. sandforce).
