How is a memory card made?

A memory card is made through a series of processes that begin with the fabrication of semiconductor materials, typically silicon. These materials are processed into integrated circuits (ICs), which are then packaged into a small card format along with a controller that manages data storage and retrieval. The card is assembled with various layers, including a protective casing, and is tested for functionality and reliability before being packaged for distribution. Finally, the cards are formatted to prepare them for use with devices.
