    摘要: As part of a memory array, a circuit is provided for altering the drive applied to an access transistor that regulates electrical communication within the memory array. In one embodiment, the circuit is used to alter the drive applied to a sense amp's voltage-pulling transistor, thereby allowing modification of the voltage-pulling rate for components of the sense amp. A sample of test data is written to the memory array and read several times at varying drive rates in order to determine the sense amp's ability to accommodate external circuitry. In another embodiment, the circuit is used to alter the drive applied to a bleeder device that regulates communication between the digit lines of the memory array and its cell plate. Slowing said communication allows defects within the memory array to have a more pronounced effect and hence increases the chances of finding such defects during testing. The circuit is configured to accept and apply a plurality of voltages, either through a contact pad or from a series of discrete voltage sources coupled to the circuit.

    摘要: An integrated circuit package having external pins includes a function circuit, such as an address buffer, receiving an input voltage through one of the pins. If the input voltage exceeds a maximum rated voltage, the function circuit can be damaged by voltage over-stress. To provide a definitive indication that the function circuit may have been over-stressed, a diode and a fuse are connected in series between the function circuit's pin and ground. When the input voltage nears the maximum rated voltage, the diode biases and applies a voltage to the fuise. The fuse is selected so that when the input voltage exceeds the maximum rated voltage, the applied voltage blows the fuse. At a later time, the function circuit can be tested for over-stress by applying a voltage to the function circuit's pin which is sufficient to forward bias the diode. If no current flows after a sufficient biasing voltage is applied to the pin, it is a definitive indication that the function circuit may have been over-stressed.

    摘要: The present disclosure includes a twist architecture useful for the data lines in a memory device. The architecture involves the twisting of four data lines to create four portions such that each data line occupies a different position in each of the four portions. Specifically, in the first portion, the first data line is adjacent to the second data line, the second data line is adjacent to the third data line, and the third data line is adjacent to the fourth data line; in the second portion, the third data line is adjacent to the first data line, the first data line is adjacent to the fourth data line, and the fourth data line is adjacent to the second data line; in the third portion, the fourth data line is adjacent to the third data line, the third data line is adjacent to the second data line, and the second data line is adjacent to the first data line; and in the fourth portion, the second data line is adjacent to the fourth data line, the fourth data line is adjacent to the first data line, and the first data line is adjacent to the third data line. Such an architecture reduces unwanted parasitic capacitive coupling between the data lines and hence improves speed.
