Flash Memory - definition
Flash memory or flash storage is a non-volatile memory which means it can store the data even if it doesn’t have any active power sources. It is an Electrically Erasable Programmable Read-Only Memory (EEPROM) which erases and rewrites data in chunks for fast, energy-efficient access and rewriting. Flash memories are mostly used in embedded systems or development boards such as Arduino, Intel Galileo, Raspberry Pi, ESP32, and so on.
