How Does Flash Memory Work?

Flash memory is a type of data storage technology that is used mainly for computers, phones, mp3 players, and video games systems. These storage systems are easily erased and reprogrammed as needed. 

You can also search online to find flash programmers for Texas instruments. These flash memory cards are very popular because of their speed and portability. But how do they work?

First, Flash memory stores data in large blocks compared to the smaller blocks in standard EEPROM. This is what keeps flash performance ahead. Flash memory is also nonvolatile, meaning that it doesn't require power to store data. 

Flash memory stores its information in an array of cells made from transistors(floating-gate transistors). Each cell contained one bit of information until recently. Modern Flashcards are multilevel cells, which allow multi-level storage based on the applied electrical charge.

Flashcards store memory by storing electric charges. Then it releases them when data is read/executed. The voltage is released in short burts, allowing a computer or machine to read it as Morse code. 

Actually binary code, you know all of the "11100011100101010111" on/off code. Although NAND flash and NOR flash can be used in completely different ways, they are both very similar systems. The output is generally the same. The output is based upon electrical charges and is interpreted as binary code.

It is the same thing as programming a memory card. Each cell is assigned a value by the voltage. That's right, your data is stored on the card as either "on" or "off". You can delete the data by doing the opposite. 

However, programming the cells can be done as needed, one word or byte at a time.
