An encryption processor, for storing encrypted data in a memory chip of a memory card, includes a FIFO memory for sequentially outputting m-bit data in response to a first signal, and an encryption key generator for generating m-bit encrypted keys (m being a positive integer) in response to a second signal and for sequentially outputting the keys in response to a third signal. A logic operator performs a logic operation on the data from the FIFO memory with the keys from the encryption key generator during a data write operation to sequentially encrypt the data. The logic operator performs a logic operation on the encrypted data received from a memory interface with the keys output from the encryption key generator during a data read operation in order to sequentially decode the encrypted data. The second signal is simultaneously generated with one of the write command or the read command.

A method for registering dialing information contemplates the steps of: inputting dialing information for storage in a dial buffer; registering in memory the dialing information stored in the dial buffer; sorting the dialing information registered in memory in an order such that the more recently registered dialing information is arranged before the less recently registered dialing information; and automatically deleting from memory dialing information which has not been redialed within a predetermined number of dialing operations. A method for searching the registered dialing information contemplates the steps of: sorting the dialing information registered in memory in an order such that the more recently registered dialing information is arranged before the less recently registered dialing information when a search key is input through a key input unit; inputting through the key input unit a keyword representing a portion or all of a telephone number corresponding to desired dialing information and then storing the input keyword in the dial buffer; searching for the dialing information corresponding to the keyword stored in the dial buffer from among the dialing information registered in memory; displaying the dialing information corresponding to the keyword; and selecting and dialing the telephone number corresponding to the displayed dialing information.

A dialing method for a telephone system begins by receiving a caller indentification (i.e., telephone number) of a party calling the telephone system. The received caller identification is then stored in a control buffer of the telephone system. A control unit of the telephone system determines whether the caller identification stored in the control buffer is identical to one of a plurality of existing caller identifications stored in a memory of the telephone system. When the caller identification stored in the control buffer is identical to one of the existing caller identifications stored in the memory, the existing caller identification that is identical to the caller identification is deleted from the memory. The caller identification is then transferred from the control buffer to the memory, and stored in the memory according to a last in first out rule. The caller identification is displayed on a display unit of the telephone system in response to a first input of a search key. Then, the telephone number corresponding to the caller identification is automatically dialed in response to input of a start key.
