Abstract: An electronic device and method in which a tuning process is performed during memory initialization, so as to reduce the occurrence of data read errors. The device may include a clock generator that generates a clock signal transmitted to a memory device, and a host control module that transmits to the memory device a change signal changing at least a portion of the clock signal, and/or a tuning related command. The host control module may receive setting data from the memory device, corresponding to at least one of the change signal and the tuning related command.

Abstract: Disclosed is a method and system for automatically updating user information in a Push-To-Talk (PTT) system. In the system, when an arbitrary user terminal performs a PTT service using a new connection number and registers user information, a PTT server transmits the new connection number and/or user information to connected group communication target terminals. Therefore, because a connection number can be automatically updated to the new connection number and the user information can be easily provided, user convenience is enhanced.

Abstract: Disclosed is a method for processing conversation information in a wireless terminal. The method includes registering information about a push-to-talk (PTT) conversation service subscriber currently performing push-to-talk conversation when a key for storing push-to-talk conversation data is input during execution of a push-to-talk conversation service, and storing push-to-talk conversation data of a subscriber of the push-to-talk wireless terminal and push-to-talk conversation data corresponding to the registered information about the push-to-talk conversation service subscriber when the push-to-talk conversation data are received. Accordingly, while PTT conversation service is being provided, PTT conversation data are stored, reproduced and then recognized, thereby ensuring reliability for a PTT conversation service which may be used only once.
