    • 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.

    • A dynamic precharge redundant circuit for a semiconductor memory device. A PMOS transistor, a fuse, a first, second and third inverters, a first switch and a second switch are applied. A source of the PMOS transistor is coupled to a voltage supply, while a gate of the PMOS transistor is to receive a precharge signal. The fuse has a ground terminal and a terminal coupled to the drain of the PMOS transistor of which the drain is further coupled to an input terminal of the first inverter. The fuse is also coupled to a column address signal. The first inverter has an output terminal coupled to an input terminal of the first switch. The second inverter has an input terminal coupled to an output terminal of the first switch and an output terminal coupled to an input terminal of the third inverter, so as to output a bit-switch control signal. An input terminal of the second switch is coupled to an output terminal of the third inverter, while an output terminal of the second switch is coupled to both the output terminal of the first switch and the input terminal of the second inverter. Thus, an error caused by the generation of an interference signal of the bit-switch control signal is prevented, so as to prevent from damaging data of the bit line sense amplifier.
