摘要： Methods and apparatus for tightening an erased bit threshold voltage distribution are disclosed. According to one aspect of the present invention, a method for processing erased bits associated with an erased bit distribution which includes an over-erased bit which has a first value that is less than a first threshold voltage value and a bit that has a second value that substantially exceeds a second threshold voltage value includes inhibiting the fast bit. The method also includes applying a soft program pulse to the erased bits such that inhibiting the fast bit substantially prevents the second value from changing and applying the soft program pulse to the over-erased bit substantially causes the first value to increase. In one embodiment, applying the soft program pulse to the over-erased bit substantially causes the first value to increase to a value that is greater than or equal to the first threshold voltage value.

摘要： A reference trimming verify circuit and method is provided for performing a program verify operation on a reference cell transistor in an array of Flash EEPROM memory cells. A reference current branch is used to generate a reference current corresponding to a predetermined overdrive voltage of the reference cell to be programmed. A drain current branch is coupled to the reference cell transistor to be programmed and generates a drain current at a fixed gate voltage applied to its control gate and at a predetermined drain voltage applied to its drain when the drain current is at the desired level. A comparator is used to compare a sensed voltage corresponding to the drain current and a reference voltage corresponding to the reference current. The comparator generates an output signal which is at a low logic level when the sensed voltage is less than the reference voltage and which is at a high logic level when the sensed voltage is greater than the reference voltage. A program pulse is applied to the reference transistor each time the comparator generates the low logic level and terminates the program pulse when the comparator generates the high logic level.

摘要： In a nonvolatile memory array that stores randomized data, the program level—the number of states per cell stored in a population of memory cells—may be determined from the aggregated results of a single read step. A circuit for aggregating binary results of a read step includes parallel transistors with control gates connected to the data latches holding the binary results, so that current flow through the combined transistors depends on the binary results.

摘要： An electrical contact (22) includes a first beam (28), a second beam (29), and a receiving cavity (20) defined between the first beam and the second beam. The first beam has a first mating face (281) facing to the receiving cavity, and the second beam has a second mating face (291) facing to the receiving cavity. The first mating face cooperates with the second mating face to form a first mating area to clamp a first area of a mating contact. The first beam has a third mating face (282). The third mating face forms a second mating area facing sidewardly to abut against a second area of a mating contact. The first beam projects sidewardly to form the third mating face.

摘要： A two-dimensional filter operates in accordance with a three-dimensional television signal having a basic layer, a reference processing unit layer and an enhancement layer. The two-dimensional filter generates a processed base layer reference picture from a base layer reference picture via a one-dimensional horizontal filter that horizontally filters the base layer reference picture to generate a first filtered base layer reference picture and a one-dimensional vertical filter, coupled to, but separable from, the one-dimensional horizontal filter, that vertically filters the first filtered base layer reference picture to generate a pre-processed base layer reference picture.
