    摘要: Methods of operating memory devices, generating reference currents in memory devices, and sensing data states of memory cells in a memory device are disclosed. One such method includes generating reference currents utilized in sense amplifier circuitry to manage leakage currents while performing a sense operation within a memory device. Another such method activates one of two serially coupled transistors along with activating and deactivating the second transistor serially coupled with the first transistor thereby regulating a current through both serially coupled transistors and establishing a particular reference current.

    摘要: Some embodiments include a memory device and a method of programming memory cells of the memory device. One such method can include applying a signal to a line associated with a memory cell, the signal being generated based on digital information. The method can also include, while the signal is applied to the line, determining whether a state of the memory cell is near a target state when the digital information has a first value, and determining whether the state of the memory cell has reached the target state when the digital information has a second value. Other embodiments including additional memory devices and methods are described.

    摘要: Methods for programming memory cells and memory devices are disclosed. One such method for programming includes performing a program verify operation of a group of memory cells. A number of potential CS2 situations are detected. If the number of detected potential CS2 situations is greater than a threshold, programming compensation for a CS2 situation is used in a subsequent programming operation.

    摘要: A selected memory cell on a selected word line is programmed through a plurality of programming pulses that are incremented by a step voltage. After a successful program verify operation, programming of the selected memory cell is inhibited while other memory cells of the selected word line are being programmed. Another program verify operation is performed on the selected memory cell. If the program verify operation fails, a bit line coupled to the selected cell is biased at the step voltage and a final programming pulse is issued to the selected word line. The selected memory cell is then locked from further programming without evaluating the final program verify operation.

    摘要: In programming a selected word line of memory cells, a first program verify or read operation is performed, after one page of a selected word line is programmed, in order to determine a first quantity of memory cells that have been programmed to a predetermined reference point in the programmed first page distribution. Prior to programming the second page of the selected word line, a second program verify or read operation is performed to determine a second quantity of cells that are still at the reference point. The difference between the first and second quantities is an indication of the quantity of cells that experienced quick charge loss. The difference is used to determine an adjustment voltage for the second page verification operation after programming of the second page.

    摘要: Memory devices and methods are disclosed to facilitate adjustment of program voltages applied during a program operation based upon erase operation cycle counter values stored in the memory device. In one such embodiment, an erase cycle counter is maintained for each block of a memory device and is stored in the associated block of memory. Programming voltage levels utilized during program operations of memory cells are determined, at least in part, based upon the value of the erase cycle counter stored in a memory block undergoing a programming operation, for example.

    摘要: The voltage of a selected word line is increased beyond the voltage to which a respective string driver transistor is capable of driving the word line by capacitively coupling a voltage to the selected word line from adjacent word lines. The voltage is capacitively coupled to the selected word line by increasing the voltages of the adjacent word lines after a programming voltage has been applied to a string driver transistor for the selected word line and after a string driver voltage has been applied to the gates of all of the string driver transistors in an array.
