    摘要: A delay time controlling circuit in a semiconductor memory device and method thereof for controlling a delay time preferably comprise a controller, a fuse unit having selectable fuse elements, a multiplexer, and a programmable variable delay circuit. With the multiplexer selecting the output of the controller, the controller generates a sequence of differing digital delay control signals to the programmable variable delay circuit in order to provide a plurality of unique delays in an output signal. When a desired time delay is monitored in the output signal, a programming signal is generated, which causes the specific digital control signal to be permanently programmed into the fuse unit via selective cutting of fuse elements. The multiplexer is then toggled via a selector fuse element to permanently select the output of the fuse unit as a control value source for the variable delay circuit.

    摘要: There are provided a synchronous RAM controlling device and method for controlling a synchronous RAM in order to access data when a burst length of a memory access is full page regardless of whether a termination access method or a wrap-around access method is used. In the synchronous RAM controlling device, an OR gate performs an OR operation on a burst stop signal for stopping input/output of data in the synchronous RAM responsive to an externally received input/output operation command signal. A counter is reset in response to the OR-operation result and counts the cycles of an external system clock signal. A burst sensor senses completion of a burst operation according to a burst length signal which is externally received and represents a burst length of at least 1 and outputs the sensed result as the burst stop signal. A control signal is input to the burst sensor which causes the burst sensor to operate the memory in one of termination or wrap-around access methods. A controller outputs the control signal, where the value of the control signal indicates termination access method when a fuse of the controller is not cut and either no logic level or a high logic level are input to an input pad of the controller. When the fuse is cut or a logic low level is input to the input pad, then the control signal output by the controller will indicate wrap-around access method.

    摘要: A column select line enable circuit prevents the first bit in a sequence of output data from being missed, thereby reducing tRCD in a synchronous memory device. The circuit delays a predetermined period of time after a row active command is applied to the memory device and then activates a column select enable line regardless of the state of the system clock signal. The column select enable line is maintained in an active state for a second period of time to allow the first bit of data to be read from the device. Thereafter, the column select enable line is enabled and disabled responsive to the system clock signal to read the remaining bits in the sequence of output data in a conventional manner. In a preferred embodiment, the circuit does not enable the column select enable line unless a decoded bank address signal is active.

    摘要: A semiconductor device having an input circuit well-suited for use in a stacked-chip configuration, results in a reduction in input capacitance, and an overall improvement in transmission speed. The semiconductor device includes at least two bonding pads which receive external electrical input signals from a shared common external pin, and at least two internal circuits, each electrically coupled to a corresponding bonding pad by a signal transmission line. The semiconductor device further includes at least two protective elements, each electrically coupled to a corresponding signal transmission line, each for protecting the internal circuits from excessive electrical transmission characteristics in the input signal. At least two fuses are electrically coupled in series between the corresponding protective element and signal transmission line. The fuses are each capable of being opened to electrically insulate the protective elements from the bonding pads and the internal circuits. By keeping only one fuse active, and opening the rest, the overall system capacitance, as viewed by the common external pin, is greatly reduced.
