To determine the memory size of a device, you can calculate it by multiplying the number of memory cells by the size of each memory cell. This will give you the total memory size of the device.
A portion of memory allocated to a device is commonly referred to as a memory-mapped I/O space or device memory. This area of memory is reserved for the device to store data related to its operations, such as buffers for input/output processing. It allows the CPU to communicate with the device by reading from and writing to specific memory addresses associated with that device. This allocation is essential for efficient data transfer and control between the CPU and peripheral devices.

The physical address stored in a special memory location in a device is commonly referred to as the "base address" or "device address." This address serves as a reference point for accessing the device's memory-mapped I/O registers or for direct memory access (DMA) operations. It allows the CPU to communicate with the device efficiently by mapping specific memory locations to the device's functions.
The maximum amount of physical memory that can be installed on this device is 16GB.
DMA Direct Memory Access DMA transfers data directly from the drive to memory w/out involving the CPU.
Memory Stick is a flash memory card. It is a data storage. In some situations it can be an input device (when you load pictures from it into an image editor), in some it can be an output device (when you write edited pictures back to your Memory Stick).
