    摘要: Problems are prevented that a refresh provides an influence to a normal access and that a continuation of write operations inhibits refresh. In a semiconductor memory device, a clock signal providing a reference to a time interval of refresh operations based on addresses corresponding to a single row s generated as a refresh clock signal. A transition of an access address “Address” externally supplied and corresponding to a memory cell is detected, so that a refresh operation is executed to a memory cell corresponding to a refresh address by triggering the generation of this detection signal before an access to a memory cell designated by the access address is made, wherein the upon input of a write enable signal /WE, the refresh is executed by triggering this signal before a write operation is executed and the refresh operation by triggering the generation of the access address is discontinued in a predetermined period of time based on the refresh clock signal.

    摘要: A voltage step-down circuit (100) that may provide an internal voltage (VINT) by reducing an external power source (VDD) has been disclosed. A voltage step-down circuit (100) may include a voltage step-down portion (10) and a compensation current source portion (20). Voltage step-down portion (10) may compare a reference voltage (VREF) with an internal voltage (VINT) and control an output current (I0) accordingly. An internal circuit (1) connected to receive internal voltage (VINT) may transition from a standby state to an active state in accordance with an activation signal. Compensation current source portion (20) may provide a compensation current (Ic) when internal circuit (1) is in a standby state. In this way, voltage step-down portion (10) may be biased to provide sufficient output current (I0) so that a response time may be improved and variations in internal voltage (VINT) may be reduced.

    摘要: A semiconductor memory device (100) including a memory cell array (MARY) and redundant memory cells (RROW) has been disclosed. A stored defect address (FA) may be programmed in a defect address storing circuit (PRG) corresponding with a defective address in the memory cell array (MARY). A controllable impedance device (TN0) may be selectively turned off to reduce a current passing through intact fuses (F01-F02 to Fn1-Fn2). The controllable impedance device (TN0) may be turned off in response to a potential applied to a pad electrode (PD), a predetermined combination of control signals (CS, OE, WE, etc.), or a reset signal (SR) generated by a power on reset circuit (PON). In this way, current may be reduced when defect address storing circuit does not have a stored defective address (FA). Also, current may be reduced during the semiconductor device characterization so that characterization results may be improved.

    摘要: The present invention provides a semiconductor memory device and control method capable of effectively suppressing the generation of operating current originating in noise of address signals provided from the outside without impairing the operating speed during reading and writing. This semiconductor memory device is provided with a filter circuit (102) for removing noise contained in address signals provided from the outside, a circuit system containing an ATD circuit (311) for generating a first address transition detection signal (&phgr;ATD1) by detecting a change in an address signal prior to passing through the filter circuit (102), and a circuit system containing an ATD circuit (321) for generating a second address transition detection signal (&phgr;ATD2) by detecting a change in an address signal after passing through the filter circuit (102). Refresh operation is controlled by first address transition detection signal (&phgr;ATD1), while read/write operation is controlled by second address transition detection signal (&phgr;ATD2). As a result, only the refresh operation is performed in the case noise has been generated, and the generation of operating current is effectively suppressed.
