What are the two types of flash memory?

There are two primary types of non-volatile flash memory devices in use today: NOR and NAND flash.

What is flash memory and its types?

Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. NAND flash and NOR flash use the same cell design, consisting of floating gate MOSFETs.

What is flash memory give two examples?

Here are a few examples of flash memory:

  • Your computer’s BIOS chip.
  • CompactFlash (most often found in digital cameras)
  • SmartMedia (most often found in digital cameras)
  • Memory Stick (most often found in digital cameras)
  • PCMCIA Type I and Type II memory cards (used as solid-state disks in laptops)

What is difference between DRAM and flash memory?

Flash memory is non-volatile and can hold data even without power, unlike RAM. … DRAM uses storage cells made up of a capacitor and a transistor. DRAM storage is dynamic — it needs a new electronic charge every few milliseconds to compensate for charge leaks from the capacitor.

Which of the following is the example of flash memory?

Flash memory is widely used with car radios, cell phones, digital cameras, PDAs, solid-state drives, tablets, and printers. The picture is an example of a MicroSD flash memory card. For additional information and examples, see our flash memory card page.
