    摘要: A memory array in a memory device is coupled to an analog I/O data interface that enables analog voltage levels to be written to the memory array. The I/O interface comprises a plurality of analog data paths that each includes a capacitor for storing charge corresponding to a target voltage to which a selected memory cell, coupled to its respective data path, is to be programmed. A plurality of comparators can be included in the I/O interface, with each such comparator coupled to a respective bit line. Such a comparator can compare a threshold voltage of a selected memory cell to its target voltage and inhibits further programming when the threshold voltage equals or exceeds the target voltage.

    摘要: The programming disturb effects in a semiconductor non-volatile memory device can be mitigated by biasing unselected memory cells with a negative voltage while a well containing the memory cells receives a positive voltage. A selected memory cell in the well can be biased with a negative voltage while the well is at the positive voltage then the selected memory cell bias transitions to a positive programming voltage when the well returns to a ground potential.

    摘要: Memory devices, methods, and sample and hold circuits are disclosed, including a memory device that includes a sample and hold circuit coupled to a bit line. One such sample and hold circuit includes a read circuit, a verify circuit, and a reference circuit. The read circuit stores a read threshold voltage that was read from a selected memory cell. The verify circuit stores a target threshold voltage that is compared to the read threshold voltage to generate an inhibit signal when the target and read threshold voltages are substantially equal. The reference circuit stores a reference threshold voltage that can be used to translate the read threshold voltage to compensate for a transistor voltage drop and/or temperature variations.

    摘要: A write algorithm is used to remove errors due to back pattern effects, cell-to-cell capacitive coupling, and program disturb in memory cells. Original data to be programmed is adjusted prior to an initial programming operation of the memory cells. The original data is then programmed into the memory cells in another programming operation. A read adjustment weight data value is associated with each series string of memory cells. The weight data value is used to compensate data read during an initial word line read. The weight data value is updated after each read and read adjustment such that the adjusted weight data value is used on the subsequent read operations.

    摘要: Methods for sensing, method for programming, memory devices, and memory systems are disclosed. In one such method for sensing, a counting circuit generates a count output and a translated count output. The count output is converted into a time varying voltage that biases a word line coupled to memory cells being sensed. Target data for each memory cell is stored in a data cache associated with that particular memory cell. When it is detected that a memory cell has turned on, the translated count output associated with the count output that is indicative of the voltage level that turned on the memory cell is compared to the target data. The comparison determines the state of the memory cell.
