What is flash memory and how does it work?
Flash memory is a type of non-volatile memory that stores data even when power is turned off. It is called “flash” because it can be erased and reprogrammed in a single operation, known as a “flash.” Flash memory works by using a series of interconnected transistors and capacitors to store electrical charges, which represent the data. The charges are stored in a floating gate transistor, which is a type of transistor that can hold a charge even when power is turned off. This allows flash memory to retain its data even when the power is turned off, making it a popular choice for portable devices and applications where data needs to be stored for long periods of time.
The way flash memory works is by using a process called tunneling to store and retrieve data. When data is written to flash memory, a high voltage is applied to the transistor, which allows the electrons to tunnel through the insulating layer and store the charge in the floating gate. When the data is read, a lower voltage is applied, and the electrons tunnel back through the insulating layer, allowing the data to be retrieved. This process is fast and efficient, making flash memory a popular choice for applications where speed and low power consumption are important. Additionally, flash memory is highly reliable and can withstand a large number of read and write cycles, making it a popular choice for applications where data needs to be stored and retrieved frequently.
