Flash memory technology
Flash memory is a type of non-volatile storage that retains data even when power is turned off. It uses floating gate transistors to store electrical charge, which represents data bits. Because it has no moving parts, flash memory is durable, fast, and compact—commonly used in USB drives, smartphones, and SSDs. Data can be written, erased, and reprogrammed electronically, making it ideal for portable and high-speed storage applications. Its efficiency and reliability have made it a key technology in modern digital devices.
