What is Flash disk ???

1. Disdventage Adventage Common flash disk Structure Definition

Definition To investigate the performance of linking sounds by the second-year students of English department to help students to form the habit of performing linking sounds in connected speech Flash memory is a non-volatile computer storage 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

Use explosion-gate transistors to save information, there are two main types of flash: nand flash and nor flash Nand flash: actions like a NAND gate Nor flash: actions like a NOR gate Structure NAND flash memory wiring and structure on silicon Nor flash memory wiring and structure on silicon

Common flash disks USB flashMultimedia Card Compact Flash Memory Stick Mini SD card

Flash memory costs far less than another device storage. It’s smaller, easy to use, easy to replace when damaged and convenient Not lose data when power is lost Advantage

Limited number of write and read data Write speed of flash data disk is low Flash memory must be completely removed a block of information before storage new data Disadvantage
