Abstract

When a memory card is inserted into a computer, a memory controller sends command information stored in a memory array to the computer. Then, the computer stores the command information received from the memory card into a RAM. The computer generates a command as needed on the basis of the stored command information and sends the generated command to the memory card. When the memory card receives the command from the computer, the memory controller analyzes the received command and performs it while making reference to command analysis information. This makes it possible to reduce a load accompanying the change and addition of commands in a semiconductor memory.
