Abstract: 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.

Abstract: A NAND architecture non-volatile memory device and programming process is described that reduces the effects of word line to word line voltage coupling by utilizing sets of two or more adjacent word lines and applying the same voltage to each in array access operations. This allows each word line of the set or pair to shield the other from word line to word line capacitive voltage coupling. In NAND memory string embodiments the various cells of strings of non-volatile memory cells are programmed utilizing modified or unmodified drain-side self boost, source-side self boost, local self boost, and virtual ground programming processes that utilize two or more “blocking” memory cells on either the source line side and drain line side of a selected memory cell. The paired blocking cells shield each other during programming to reduce coupled noise, to prevent charge leakage from the boosted channel of the selected memory cell.

Abstract: Embodiments of the present disclosure provide methods, devices, modules, and systems for reading non-volatile multilevel memory cells. One method includes receiving a request to read data stored in a first cell of a first word line, performing a read operation on an adjacent cell of a second word line in response to the request, determining whether the first cell is in a disturbed condition based on the read operation. The method includes reading data stored in the first cell in response to the read request by applying a read reference voltage to the first word line and adjusting a sensing parameter if the first cell is in the disturbed condition.

In a method of operation, the second voltage pulse occurs a first delay period after the first voltage pulse and the third voltage pulse occurs a second delay period after the second voltage pulse, the second delay period being different from the first delay period.

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: A single latch circuit is coupled to each bit line in a multiple level cell memory device to handle reading multiple data bits. The circuit is comprised of a latch having an inverted node and a non-inverted node. A first control transistor selectively couples the non-inverted node to a latch output. A second control transistor selectively couples the inverted node to the latch output. A reset transistor is coupled between the inverted node and circuit ground to selectively ground the circuit when the transistor is turned on.
