摘要： An external high/low voltage compatible semiconductor memory device includes an internal voltage pad, an internal voltage generation circuit, and an internal voltage control signal generation circuit. The internal voltage pad connects a low external voltage with an internal voltage, and the internal voltage generation circuit generates an internal voltage in response to an internal voltage control signal and a high external voltage. The internal voltage control signal generation circuit generates an internal voltage control signal according to an high or low external voltage. Thus, a database of the semiconductor memory device can be managed without classifying the database into databases for the high voltage and databases for the low voltage because of the internal voltage control signal. In addition, the internal voltage level is stable because charges provided to the internal voltage are regulated according to a voltage level of the external voltage.

摘要： Semiconductor devices and methods of sampling data therefrom are provided in which data is sampled from a memory cell array based on a relative position of a memory cell array section that contains the data. A sense amplifier generates an output signal in response to an address of one or more cells in a memory cell array. A control circuit generates a sample control signal in response to at least a portion of the address (e.g., one or more high order bits of the address) of the one or more cells in the memory cell array. A data sampling circuit then samples the output signal of the sense amplifier in response to the sample control signal. The portion of the memory cell array address used to drive the control circuit may logically divide the memory cell array into two or more sections. The control circuit may adjust the timing of the sample control signal in accordance with the proximity of a memory cell array section to the sense amplifier.

摘要： A circuit for generating an internal source voltage signal responsive to an external source voltage signal in a semiconductor memory device prevents malfunction and extends the lifetime of the device by clamping the internal source signal if the device is in a normal operating mode when the external source signal is in a stress operating range. When the device is placed in a test mode, the circuit allows the internal source signal to increase in proportion to the level of the external source signal when the external source signal is in a stress operating range. The circuit includes in internal source voltage generator, which always clamps the internal source signal when the external source signal is in a normal operating range, and a pull-up unit which is activated in response to a control signal. The control signal is enabled when the device is placed in a test mode by combining external timing signals.
