    摘要: A memory device which includes several partially defective memory chips and a control circuit (1) for receiving an address signal corresponding to a storage cell address of each of the partially defective memory chips, and for controlling, in response to the address signal, the partially defective memory chips such that only one thereof is enabled.
    The control circuit according to the invention can be implemented to control the chip driver circuit of a variety of different sizes of memory chips. For example, the control circuit can be implemented for controlling the chip driver circuit of a one-quarter size memory chip, a one-half size memory chip, a three-quarter size memory chip, or a full-size memory chip.

    摘要: Memory system comprising dynamic memory cells, wherein each cell comprises a switchable cell device (10) and a capacitive node (12), wherein said switchable cell device [10) is connected to a bit line (14) to read the charge stored at said (12) node and to a first word line (16) to selectively switch said cell device (10) responsive to a first signal in said word line (16).
    Means are provided for rewriting the cell after reading without discharging the bit line to thereby improve cycle time. The cell includes an independently operated device (24) to access the capacitive storage node (12) to discharge the node of any charge thereon after the reading of a low or no charge bit on the capacitive storage node.

    摘要: The present invention provides an apparatus and method for monitoring the functioning of a special operational mode on an integrated circuit module (20) without the need for a special or dedicated pin. By monitoring the data output pins (47) of the module operation in a special operational mode and premature interruption thereof, is detected. Delayed transition from a state of low impedance to a state of high impedance during the data output cycle is indicative of the special operational mode. The modules (20) which usually have tri-state devices (22) on their output lines (47) are provided with delay circuitry to delay the transition of the tri-state device (22), during the data output cycle, from a state of low impedance to a state of high impedance while the device remains in a special operating mode.

    摘要: A dual sense amplifier construction with divided bit line isolation. A switch is disposed at approximately the midpoint of a bit line to divide the bit line into first and second bit line segments. When opened, the switch provides electrical isolation between the first and second bit line segments so that an accessed memory charge can be isolated from one-half of the capacitance associated with the bit line. Once the isolated memory charge is read and pre-amplified, the remaining bit line capacitance is no longer of concern. The switch is then closed to provide electrical connection between the first and second bit line segments, thereby allowing the completion of the amplification operation.
