FLASH MEMORY,[object Object],[object Object]
Non-volatile = that can retain information even when not powered
There are two main types of Flash Memory :
NOR Flash
NAND Flash
Flash Memory stores information in an array of floating gates transistors
Flash transistors are similar to standard MOS transistors except that they have two gates instead of just one :
On top is the control gate
Below is the floating gate,[object Object]
