    摘要: A multi-headed word line driver circuit incorporates bent-gate transistors to reduce the pitch otherwise achievable for interfacing to tightly-pitched array lines. In certain exemplary embodiments, a three-dimensional memory array includes multiple memory blocks and array lines traversing horizontally across at least one memory block. Vertical active area stripes are disposed beneath a first memory block, and a respective plurality of bent-gate electrodes intersects each respective active area stripe to define individual source/drain regions. Every other source/drain region is coupled to a bias node for the active area stripe, and remaining source/drain regions are respectively coupled to a respective array line associated with the first memory block, thereby forming a respective first driver transistor for the respective array line. In certain embodiments, a respective plurality of complementary array line driver circuits is disposed on each side of a connection area between adjacent memory blocks, and each such driver circuit is responsive to a single driver input node.

    摘要: A nonvolatile memory cell comprising a diode formed of semiconductor material can store memory states by changing the resistance of the semiconductor material by application of a set pulse (decreasing resistance) or a reset pulse (increasing resistance.) In preferred embodiments, set pulses are applied with the diode under forward bias, while reset pulses are applied with the diode in reverse bias. By switching resistivity of the semiconductor material of the diode, a memory cell can be either one-time programmable or rewriteable, and can achieve two, three, four, or more distinct data states.

The method includes initializing a program voltage and program time interval; selecting a memory cell to be programmed within the three-dimensional memory having the plurality of levels of memory cells; applying a pulse having the program voltage and the program time interval to the selected memory cell; performing a read after write operation with respect to the selected memory cell to determine a measured threshold voltage value; and comparing the measured threshold voltage value to a minimum program voltage. In response to the comparison between the measured threshold voltage value and the minimum program voltage, the method further includes selectively applying at least one subsequent program pulse to the selected memory cell.

    摘要: A storage system and method for forming a storage system that uses punch-through diodes as a steering element in series with a reversible resistivity-switching element is described. The punch-through diode allows bipolar operation of a cross-point memory array. The punch-through diode may have a symmetrical non-linear current/voltage relationship. The punch-through diode has a high current at high bias for selected cells and a low leakage current at low bias for unselected cells. Therefore, it is compatible with bipolar switching in cross-point memory arrays having resistive switching elements. The punch-through diode may be a N+/P−/N+ device or a P+/N−/P+ device.
