What is flash memory

 Flash memory is a form of semiconductor memory . It was first introduced in mid 1980. These memories can be reprogrammed at high speed. These are electronic random access memory. It is        non volatile in nature . In flash memory the entire memory can be erased in few seconds by using electric erasing technology . It is used in many input output devices. It is also used to store data and     programming algorithm in cell phones , Digital cameras and MP3 music player . Basically flash memory falls in between EPROM and EEPROM.

There are two kinds of flash memory :-

1.  Code storage flash :- It is made by Intel , AMD , Atmel etc . It stores programming algorithm and largely found in cell phones .
2.  Data storage flash :- It is made by Sandisk , Tosiba etc. It stores data and comes in digital cameras and MP3 players .
