SanDisk 4GB microSDHC with USB Reader and SD Adapter

SanDisk 4GB microSDHC with USB Reader and SD AdapterThere are two common ways to go about addressing your media storage needs. If you have to transport large amounts of files with even larger file sizes, then the best option is to get an external portable hard disk drive. While it may be a bit bulky, most portable hard disk drives today can store all sorts of files with memory capacities ranging from 100 gigabytes up to a whopping 500 gigabytes. However, if what you need is something that will fit right into your shirt’s pocket, then you may have to go with flash memory. In comparison with portable hard drives, flash memory does have a smaller memory capacity. The portability it affords users though, still makes it a much sought-after choice amongst people who are always on the go. One of these products is the Sandisk 4GB microSDHC with USB Reader and SD Adapter.

Samsung Develops Even Smaller, Denser Flash Memory Technology

flash memory in current formSamsung Electronics Co. has developed a more advanced flash memory chip that will allow increased data storage in digital products such as music players. Samsung, the largest manufacturer of computer memory chips, unveiled a 64-gigabit NAND flash memory chip based on process technology much finer than previously used. This is accomplished by utilizing circuit elements that are 30 nanometers wide.

Nanocrystals may yield Higher Capacity Flash Memory

With recent developments by Nanosys, new confidence of doubling flash memory capacity has grown with self-assembling metal nanocrystals added to the process.

As reported by Technology Review, “You end up with something that looks like a bunch of skyscrapers,” says Don Barnetson, director of market development for nonvolatile memory products at Nanosys. These skyscrapers electrically interact with each other in undesirable ways that can make the chip unreliable. Flash-memory cells hold electrons, which represent bits of data, on a small piece of polysilicon called a floating gate. The floating gate is surrounded by a thick layer of insulating material that keeps the electrons from leaking out. But as the cells shrink, they begin to electrically interfere with each other. By replacing the floating gate with nanocrystals, explains Barnetson, engineers can reduce the amount of insulating material needed and shorten the cells, eliminating the interference.
