In integrated circuits, circuits with storage function without physical form are also called memories, such as RAM and FIFO.
In the system, the physical storage device is also called the memory, and all the information in the computer, including the input original data, computer programs, intermediate running results and final running results, are stored in the memory.

Digital film: The storage medium of digital camera belongs to the same digital storage medium as sm card of Hitachi, sd card of Panasonic and memorystick of Sony.
2. Features
Excellent performance supports high concurrency and bandwidth saturation utilization. The storage system separates the control flow from the data flow, and multiple storage servers provide services to the outside world at the same time when accessing data, thus achieving high concurrent access.
Whether the system is powered by battery or commercial power supply, the application requirements will determine the type and purpose of memory. In addition, the size and cost of memory are also important factors to be considered in the selection process.
