    Abstract: A semiconductor memory device with a function of equalizing voltages of dataline pair. After turning off the word line and before turning on the equalization means, the datalines are precharged and discharged to a supplied voltage and ground, respectively. Using the theory of uniform distribution of charges, the datalines are equalized into VCC/2, that is, a half of the source supply voltage. The interference on a weak voltage VCC/2 generator within the equalization means during the equalization mode is thus avoided. The equalization of voltages on the dataline pair can be achieved within a transient cycle. Complete data can thus be written or read before the next command is given.

    Abstract: A method for verifying a server end apparatus, suitable for verifying the identity of a server end apparatus from a client end apparatus, is provided. In the present invention, authentication data is sent to the server end apparatus by the client end apparatus, such that the server end apparatus verifies the authentication data. Afterwards, the server end apparatus must return an initial number, which is preset by the user, to the client end apparatus to verify whether the initial number is correct or not. If the initial number is incorrect, the connection with the server end apparatus is shut down. Therefore, the efficiency for verifying the server end identity is strengthened, so as to enhance the security.
