What technology is USB flash memory based on?

USB flash memory is based on solid state technology, which utilizes electronically erasable programmable read-only memory (EEPROM) or flash memory chips. This type of storage is characterized by the absence of moving parts, making it more durable and reliable compared to traditional storage methods like magnetic or optical storage.

Solid state technology allows data to be read from and written to flash memory cells in a way that is faster and more efficient than older technologies, contributing to the compact size and portability of USB flash drives. The solid state design also enables USB flash memory devices to have a lower power consumption and increased resistance to physical shock, which are significant advantages in everyday use and for data storage purposes.
