Flash memory is a long-life and non-volatile storage chip that is widely used in embedded systems. It can keep stored data and information even when the power is off. It can be electrically erased and reprogrammed. Flash memory was developed from EEPROM (electronically erasable programmable read-only memory).
Why do devices use flash memory?
Flash memory is fast to access and write to, although not as fast as when reading from or writing to RAM. It requires little power and contains no moving parts, making it an ideal storage medium for many modern devices, such as tablets, smartphones and digital cameras.
Why is flash memory used instead of ROM?
Flash memory combines the advantages of ROM and RAM. It not only has the electrically erasable and programmable capability (EEPROM), but also can read data quickly without power loss (the advantage of NVRAM). This memory is used in USB and MP3.
Do cell phones use flash memory?
Flash memory is inside your smartphone, GPS, MP3 player, digital camera, PC and the USB drive on your key chain. Solid-state drives (SSD) using flash memory are replacing hard drives in netbooks and PCs and even some server installations.
What are the advantages of USB?
One of the main benefits of using USB cables is their ability to carry more information per second (12 mb/second) than parallel cables (115 kb/second). This means faster data transfer. Another advantage that goes with an USB cable is that its port is smaller than parallel cable port.
Is flash memory RAM or ROM?
Flash memory: A special type of memory that works like both RAM and ROM. You can write information to flash memory, like you can with RAM, but that information isn’t erased when the power is off, like it is with ROM.
Which is faster RAM or ROM?
Key Difference between RAM and ROM
RAM is random access memory and cannot hold the data without the power, whereas ROM is a read-only memory and can hold the data even without the power. … With RAM, writing data is a much faster and lightening process, whereas ROM, writing data speed is much slower as compared to RAM.
Is ROM physical memory?
ROM is an acronym for Read-Only Memory. It refers to computer memory chips containing permanent or semi-permanent data. Unlike RAM, ROM is non-volatile; even after you turn off your computer, the contents of ROM will remain. Almost every computer comes with a small amount of ROM containing the boot firmware.
