    摘要: Techniques and corresponding circuitry are presented for the detection of wordline leakage in a memory array. In an exemplary embodiment, a capacitive voltage divider is used to translate the high voltage drop to low voltage drop that can be compared with a reference voltage to determine the voltage drop due to leakage. An on-chip self calibration method can help assure the accuracy of this technique for detecting leakage limit.

    摘要: Techniques for a post-write read are presented. In an exemplary embodiment, a combined simultaneous sensing of multiple word lines is used in order to identify a problem in one or more of these word lines. That is, sensing voltages are concurrently applied to the control gates of more than one memory cell whose resultant conductance is measured on the same bit line. The combined sensing result is use for measuring certain statistics of the cell voltage distribution (CVD) of multiple word lines and comparing it to the expected value. In case the measured statistics are different than expected, this may indicate that one or more of the sensed word lines may exhibit a failure and more thorough examination of the group of word lines can be performed.

    摘要: An insulator is disclosed, which includes an insulating surface. A part of the insulating surface is applied with a conductive coating having a specific resistivity. A conductive coating region having the specific resistivity and a nonconductive coating region are configured that: in a dry environment, no continuous conductive channel exists between upper and lower fittings of the insulator. The value of the leakage current that can be caused by the conductive coating region having the specific resistivity on the insulating surface enables the insulating surface to reach an ice-proof temperature in an icing climate condition. Also, a power transmission apparatus in which the insulator is adopted is disclosed. In an icing climate condition, the conductive coating can achieve the function of increasing the value of the leakage current on the surface of the insulator, so as to prevent the ice formation.
