Nand Flash memory

Nand Flash memory is the latest technology which is happenning recently. We can see such types of memory devices in an I-pod nano from apple. They are compact and very efficient have better write cycle ratio and are way better than hard drives. This is an important issue when it comeos to space.. as in cellphones, digital cameras or robots where it is good to have a memory device which is smaller and lightweight. Samsung is going to launch nand flash memories upto 16gb by the end of 2006. You can read a general introduction to nonvolatile memory here : http://aplawrence.com/Makwana/nonvolmem.html

Also there is an application note from freescale ( motorola ) which is titled, “Non-volatile memory overview”. The freescale website has the pdf file of the article.

I read somewhere that there are 1 inch harddrives on the market to be used in cell phones or digital cameras which can store upto 6 gb of data. This is interesting.. cause the smallest harddrives were about 1.8 inch in size, last year. Toshiba and seagate are manufacturing these devices along with sony.
