    摘要: A method and system for forming, resetting, or setting memory cells is disclosed. One or more programming conditions to apply to a memory cell having a reversible resistivity-switching element may be determined based on its resistance. The determination of one or more programming conditions may also be based on a pre-determined algorithm that may be based on properties of the memory cell. The one or more programming conditions may include a programming voltage and a current limit. For example, the magnitude of the programming voltage may be based on the resistance. As another example, the width of a programming voltage pulse may be based on the resistance. In some embodiments, a current limit used during programming is determined based on the memory cell resistance.

    摘要: An integrated circuit is provided including at least one memory cell. Such memory cell, in turn, includes a transistor and a capacitor. The transistor includes a source, a drain, and a gate. Further, the capacitor includes a well and a gate. The gate of the transistor remains in communication with the gate of the capacitor.

In such embodiments, the well of the transistor abuts the well of the capacitor. In still further embodiments, for a more compact design, a diffusion region of the transistor is situated less than 2.5 μm from a diffusion region of the capacitor.

    摘要: A semiconductor p-i-n diode and method for forming the same are described herein. In one aspect, a SiGe region is formed between a region doped to have one conductivity (either p+ or n+) and an electrical contact to the p-i-n diode. The SiGe region may serve to lower the contact resistance, which may increase the forward bias current. The doped region extends below the SiGe region such that it is between the SiGe region and an intrinsic region of the diode. The p-i-n diode may be formed from silicon. The doped region below the SiGe region may serve to keep the reverse bias current from increasing as result of the added SiGe region. In one embodiment, the SiGe is formed such that the forward bias current of an up-pointing p-i-n diode in a memory array substantially matches the forward bias current of a down-pointing p-i-n diode which may achieve better switching results when these diodes are used with the R/W material in a 3D memory array.

    摘要: Shrinking the dimensions of PMOS or NMOS thin film transistors is limited by dopant diffusion. In these devices an undoped or lightly doped channel region is interposed between heavily doped source and drain regions. When the device is built with very short gate length, source and drain dopants will diffuse into the channel, potentially shorting it and ruining the device. A suite of innovations is described which may be used in various combinations to minimize dopant diffusion during fabrication of a PMOS or NMOS polycrystalline thin film transistor, resulting in a highly scalable thin film transistor. This transistor is particularly suitable for use in a monolithic three dimensional array of stacked device levels.

    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.
