Abstract: Methods for sensing, memory devices, and memory systems are disclosed. One such method for sensing includes charging bit lines of an all bit line architecture to a precharge voltage, selecting a word line, and performing a sense operation on the bit lines.

Abstract: 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.

Abstract: Methods of programming a memory, memory devices, and systems are disclosed, for example. In one such method, each data line of a memory to be programmed is biased differently depending upon whether one or more of the data lines adjacent the data line are inhibited. In one such system, a connection circuit provides data corresponding to the inhibit status of a target data line to page buffers associated with data lines adjacent to the target data line.

Abstract: In one or more of the disclosed embodiments, a read operation is compensated for back pattern effect. A bit line current is generated by a read operation that biases the word lines. As part of a back pattern effect measurement phase, at predetermined time intervals an indication of the discharge status of the bit line is stored in a latch of a set of N latches coupled to each bit line. At the end of the measurement phase, the set of latches contains a multiple bit word that is an indication of the back pattern effect experienced by that particular series string of memory cells. This back pattern effect indication is used in subsequent read operations to adjust the timing of the operation.

The second programming pulse step voltage magnitude can be less than the first programming pulse step voltage magnitude.
