What is Flash Memory?

Explanation:
Flash memory is a type of nonvolatile storage that can be erased electronically and rewritten. That means it keeps data even when power is removed, unlike RAM which loses data when powered off. It’s different from ROM, which is nonvolatile but generally read-only and not changed during normal use, and from cache, which is a tiny, fast memory close to the CPU and usually volatile. Flash memory stores data in cells that can be electrically erased and repurposed, though erasing occurs in larger blocks and rewriting involves an erase cycle. This combination of persistence and rewritability makes flash memory ideal for USB drives, SSDs, and memory cards.
