Did you know that who was the inventor of Flash Disk (USB)? until today, a small object is almost always exist in our pockets because it has become the part of our daily life like a pen in the past.

The Definition of Flash

USB (Universal Serial Bus) or most commonly Flash Disk (Flash Drives) are data storage devices NAND type of Flash Memory that has a built-in USB interface, discovery Flash Memory (NOR and NAND) by Dr. Fujio Masuoka in 1984 while working on Toshiba flash while the name was given by his colleagues that Mr. Shoji Ariizumi. Flash these drives are usually small, lightweight, and can be read and written in addition to the USB flash drive also has many advantages over other data storage devices, particularly the floppy disk. This tool is faster, smaller, with greater capacity and more reliable (because it has no moving parts) than a disk. the capacity is available for USB flash drive there from 128 megabytes to 64 gigabytes per November 2006.

It is not clear who developed it first because there are three companies that argue that M-Systems, Netac, and Trek 2000. Not only are growing in size, but the shape and function is also changing. There is a flash drive that uses a rotary design so that we do not have to worry about losing the lid. There is also a flash drive so waterproof rubber coated or equipped with a carabineer clip so easy hanging. In fact it has made a flash drive shaped credit card models. His name is wallet-friendly USB. The size is only 86 x 54 x 1.9 mm. Thus, it can be stored safely in a wallet.

Knowing NAND and NOR Gate

Here following what is the NAND and NOR Gate:

  • NAND Gate: The output is high when either of inputs A or B is high, or if neither is high. In other words, it is normally high, going low only if both A and B are high.
  • The NAND gate operates as an AND gate followed by a NOT gate. It acts in the manner of the logical operation "and" followed by negation. The output is "false" if both inputs are "true." Otherwise, the output is "true."

  • NOR Gate: The output is high only when neither A nor B is high. That is, it is normally high but any kind of non-zero input will take it low. The NOR gate is a combination OR gate followed by an inverter. Its output is "true" if both inputs are "false." Otherwise, the output is "false."

The NOR gate and the NAND gate can be said to be universal gates since combinations of them can be used to accomplish any of the basic operations and can thus produce an inverter, an OR gate or an AND gate. The non-inverting gates do not have this versatility since they can't produce an invert.

Security System on the Flash

For security issues owned flash drives currently limited to protect the data that is not accessible by people who are not owners. How it works in use today include the use of full disk encryption or physical authentication tokens. New system was introduced mid-year 2005 is biometric fingerprinting. However, this method is very expensive because the securities using high-tech.
So actually the inventor of the flash itself until now unclear (still disputed copyright (inheritance fight over ownership of treasure), but which certainly dash Dr. Fuji Masuoka for his pioneering 1984 who discovered the "Flash Memory" (stub of a flash disk).

In fact, the use of flash drives has grown to a variety of things. For example, the steps of setting up the flash drive to boot Windows XP. The main requirement is the motherboard and the BIOS of the computer we can support the management of booting from a flash drive. Some applications can also be run from a flash drive without having to install it first to the computer.
