摘要： A semiconductor memory device includes an address transition detection circuit for detecting the state transition of address signals and generating a pulse having a predetermined pulse width, a precharge circuit for generating and equalizing a pair of input/output lines in response to the output pulse of the address transition detection circuit, address decoder circuit for decoding the address signals and generating an address selection signal, and a gate circuit connecting the pair of input/output lines to a selected pair of bit lines in response to the address selection signal of the address decoder circuit. In the device, the address decoder circuit has a signal delay characteristic for delaying signals from the state transition of the address signal until the completion of the precharge and equalization of the I/O lines. Accordingly, the access time of the memory address can be operated in high speed by forming the address decoder independent of an ATD pulse, and the circuit can be easily designed and the cost can be saved by eliminating the wiring between the ATD circuit and the address decoder.

摘要： A security method and a security apparatus are disclosed which use a self-generated encryption key. The security method includes the steps of: generating an encryption key; decrypting pre-encrypted data using a pre-stored manufacturer key; and re-encrypting the decrypted data using the encryption key. The security method and apparatus minimize external leakage of data by self-generating the unique encryption key. Since the encryption keys are unique in each set, set binding is possible.

摘要： Provided are a video data recording method and apparatus having a portion hiding function and a video data reproducing method and apparatus thereby. The video data recording method comprises: displaying a video by decoding the bitstream and simultaneously storing the bitstream in a predetermined storage unit; determining a position of a hidden area in response to an portion hiding command issued by a user viewing the displayed video; and storing position information of the hidden area in the storage unit by being correlated the position information with the bitstream. According to an embodiment of the present invention, a user can easily generate a video program with hidden areas without directly editing the video program to prevent specific portions of a recorded video program from being viewed by an unauthorized user. A function allowing the specific portions to be hidden is initiated by a simple operation of a remote control when the video program is recorded.

摘要： A data output buffer includes an output driving stage having a pair of parallel pull-up transistors and a pull-down transistor, a latch circuit for latching a pair of complementary signals, a second gate for gating the non-inverted output signal of the latch circuit in response to an external output enable signal and then supplying it to the gate of one pull-up transistor of the output driving state, a third gate also for gating the non-inverted output signal of the latch circuit in response to an external output enable signal, and a selective bootstrap circuit for driving the other pull-up transistor of the output driving stage. The output driving stage is driven to an external supply voltage when the external supply voltage is higher than a set voltage, and is driven to a boosted voltage when the external supply voltage is lower than the set voltage, determined by output signals from the second and third gates.

摘要： An output feedback control circuit for an integrated circuit (IC) device is disclosed which includes an I/O line sense amplifier for amplifying the weak signals read out from cells, a read driver for amplifying the output of the I/O line sense amplifier, an output latch/transmission block for latching or transmitting the output signals of the read driver, a precharge block for precharging the output node of the output latch/transmission block, and a state transition detecting block for generating feedback control clocks. If the circuit of the present invention is installed to the output terminal of an IC decive, the data latched at the output node can be maintained regardless of the intruding of an external noise until a precharge clock is generated at a new cycle. Further, the sense amplifier and the read driver are disabled after having amplified the input signals within a single cycle, and therefore, the DC power consumption can be prevented.
