摘要： Verifying good electrical contact between pads of multiple circuit dies and a probe card or test device, where the driver channels of the test device or probe card device are connected in parallel to corresponding contacts on the circuit dies. Each of a plurality of test device or probe card device driver channels are connected to a corresponding one of a plurality of contacts on each of the plurality of circuit dies such that each test device driver channel is shared among a corresponding contact on each of said plurality of circuit dies. Logic circuitry on each chip connects each of the plurality of contacts to at least one designated contact to output from the device via said at least one designated contact a voltage that corresponds to a voltage at one of said plurality of contacts when a voltage is applied to said one of said plurality of contacts. A voltage is applied at the test device driver channel and the voltage on the designated contact of each of the circuit dies that is coupled to said plurality of contacts on the circuit die is evaluated to determine whether contact is made between the test device driver channel pin or terminal (either directly or via or probe card) and the corresponding contact on each of said plurality of circuit dies.

摘要： A self-refresh module includes an oscillator configured to provide a first signal having a first frequency, a trimming divider configured to trim the first signal to provide a second signal having a second frequency, and a temperature sensor configured to sense a temperature of the memory device and provide a temperature signal. The self-refresh module includes a temperature look-up table configured to receive the temperature signal and provide a third signal based on the temperature signal, and a temperature divider configured to provide a self-refresh pulse signal based on the second signal and the third signal.

摘要： A memory device (10) includes an array (12) of memory cells arranged in rows and columns. Preferably, each memory cell includes a pass transistor coupled to a storage capacitor. A row decoder (18) is coupled to rows of memory cells while a column decoder (14) is coupled to columns of the memory cells. A refresh controller (19) is adapted to generate memory cell addresses for array (12) during a refresh sequence. In a preferred embodiment of the present invention, the refresh controller ensures that no shared sense amplifiers (24) are activated during consecutive refresh cycles, allowing a portion or all of the time required for precharging the bitlines to be saved. In a preferred embodiment, consecutive refresh cycles can be located closer together in time because a second refresh cycle may be initiated prior to the completion of a first refresh cycle.

摘要： An Insulated Gate Field Effect Transistor (IGFET), fabricated using Shallow Trench Isolation (STI), has an edge of a channel region of the IGFET which has a curved shape with a controlled radius of curvature so as to reduce the electric field at the edge of the channel region. A method of controlling the shape of the edge of the channel region is to limit the supply of oxygen to the region at the edge of the channel region during the oxidation process when the side walls of the silicon island, in which the transistor will be formed, are initially covered with a layer of silicon oxide.

摘要： A semiconductor memory device is provided that uses a single wordline to access both storage cells of a so-called twin cell. A memory device comprises a plurality of wordlines and a plurality of bitlines in an array, with a plurality of storage cells at certain intersections of wordlines and bitlines. A plurality of sense amplifiers are provided, each of which is connected to at least a first pair of bitlines to detect a voltage difference on the bitlines caused by the charge from a twin storage cell comprised of first and second storage cells at the intersection of a single wordline with said first pair of bitlines, respectively. As a result, each cell of a twin storage cell can be accessed with a single wordline.
