An SD Memory Card follows a simple design that consists of a printed circuit board and a set of memory chips. The card uses non-volatile memory to store data, meaning that the data remains even when the device is powered off.

When an SD card is inserted into a device, such as a digital camera, the device initiates a connection with the card. Once the connection is established, the device can read and write data to the card. The amount of data that can be stored on the card depends on its capacity, which ranges from a few gigabytes to several terabytes.
