Flash memory is non-volatile computer memory that can be electrically erased and reprogrammed. It is a technology that is primarily used in memory cards and USB flash drives for general storage and transfer of data between computers and other digital products. It is a specific type of EEPROM (Electrically Erasable Programmable Read-Only Memory) that is erased and programmed in large blocks; in early flash the entire chip had to be erased at once. Flash memory costs far less than byte-programmable EEPROM and therefore has become the dominant technology wherever a significant amount of non-volatile, solid state storage is needed. Example applications include PDAs (personal digital assistants), laptop computers, digital audio players, digital cameras and mobile phones. It has also gained popularity in the game console market, where it is often used instead of EEPROMs or battery-powered SRAM for game save data.

Flash memory is non-volatile, which means that no power is needed to maintain the information stored in the chip. In addition, flash memory offers fast read access times (although not as fast as volatile DRAM memory used for main memory in PCs) and better kinetic shock resistance than hard disks. These characteristics explain the popularity of flash memory in portable devices. Another feature of flash memory is that when packaged in a "memory card," it is enormously durable, being able to withstand intense pressure, extremes of temperature, and even immersion in water.

Although technically a type of EEPROM, the term "EEPROM" is generally used to refer specifically to non-flash EEPROM which is erasable in small blocks, typically bytes. Because erase cycles are slow, the large block sizes used in flash memory erasing give it a significant speed advantage over old-style EEPROM when writing large amounts of data.

Print Article Difficulty: Easy

Tips & Warnings:

  • Watch my video for a clear understanding.
  • This process is the same for all versions of windows
  • Copy more than one file or folder at a time by holding down Ctrl key while you click multiple folders or files.
  • Folders are yellow and they hold files. Files reside inside folders.
  • Folders are used to organize your data files.
Step1
Open my computer
Step2
Click the source drive and browse to the file or folder to be copied
Step3
Open a 2nd my computer window and browse to the destination folder. You can also copy directly to the root of the destination drive.
Step4
Using the left mouse button, Click and hold on the file or folder in the source window. Drag the file to the new location and verify that there is a PLUS + next to your mouse cursor. Now release the left mouse button. The file is now being copied.
