In a password authenticating apparatus, a control section displays an image of a keyboard including multiple character keys on a display section. An input section sends input data to the control section on reception of an input of a position on a display screen. In connection with the displayed keyboard, the control section specifies a character corresponding to the input position as an input character, checks the input character against a character that forms a registered password, determines whether the input character is correct, and holds a determination result. Then, after the input character is determined, a display is changed to an image of the keyboard for receiving a next character input. Then, in connection with all characters that form the password, authentication is determined as being OK when all held determination results are correct.

Music is blanket transmitted (for example, via satellite downlink transmission) to each customer's user station where selected music files are recorded. Customers preselect from a list of available music in advance using an interactive screen selector, and pay only for music that they choose to playback for their enjoyment. An antipiracy “ID tag” is woven into the recorded music so that any illegal copies therefrom may be traced to the purchase transaction. Music is transmitted on a fixed schedule or through an active scheduling process that monitors music requests from all or a subset of satellite receivers and adjust scheduling according to demand for various CD's. Receivers store selections that are likely to be preferred by a specific customer. In those instances where weather conditions, motion of atmospheric layers or dish obstructions result in data loss, the system downloads the next transmission of the requested CD and uses both transmissions to produce a “good copy”. In conjunction with the blanket transmission of more popular music, an automated CD manufacturing facility may be provided to manufacture CD's that are not frequently requested and distribute them by ground transportation.

While a semiconductor memory operates in a first operation mode with high security, an encrypted command is inputted and then decoded to acquire the first address information. After the semiconductor memory comes into a second operation mode where the level of security is lower than that of the first operation mode, a command is inputted. Then, the second address information is acquired from the command. A control circuit in the semiconductor memory generates an address of 10 bits by using the first address information as a high-order 4 bits and the second address information as a low-order 6 bits and outputs the address to a memory array. With this operation, it becomes possible to read / write data from / to the memory array.
