    摘要: The present invention provides apparatus, methods, and systems for a memory layer layout for a three-dimensional memory. The memory layer includes a plurality of memory array blocks; a plurality of memory lines coupled to the memory array blocks; and a plurality of zia contact areas for coupling the memory layer to other memory layers in a three-dimensional memory. The memory lines extend from the memory array blocks and are formed using a sidewall defined process. The memory lines have a half pitch dimension smaller than the nominal minimum feature size capability of a lithography tool used in forming the memory lines. The zia contact areas have a dimension that is approximately four times the half pitch dimension of the memory lines. The memory lines are arranged in a pattern adapted to allow a single memory line to intersect a single zia contact area and to provide area between other memory lines for other zia contact areas. Numerous additional aspects are disclosed.

    摘要: Methods are described to fabricate, program, and sense a multilevel one-time-programmable memory cell including a steering element such as a diode and two, three, or more dielectric antifuses in series. The antifuses may be of different thicknesses, or may be formed of dielectric materials having different dielectric constants, or both. The antifuses and programming pulses are selected such that when the cell is programmed, the largest voltage drop in the memory cell is across only one of the antifuses, while the other antifuses allow some leakage current. In some embodiments, the antifuse with the largest voltage drop breaks down, while the other antifuses remain intact. In this way, the antifuses can be broken down individually, so a memory cell having two, three, or more antifuses may achieve any of three, four, or more unique data states.

    摘要: A one-time field programmable (OTP) memory cell with related manufacturing and programming techniques is disclosed. An OTP memory cell in accordance with one embodiment includes at least one resistance change element in series with a steering element. The memory cell is field programmed using a reverse bias operation that can reduce leakage currents through the array as well as decrease voltage levels that driver circuitry must normally produce in program operations. An array of memory cells can be fabricated by switching the memory cells from their initial virgin state to a second resistance state during the manufacturing process. In one embodiment, the factory switching operation can include popping an anti-fuse of each memory cell to set them into the second resistance state. The array of memory cells in the second resistance state are provided to an end-user. Control circuitry is also provided with the memory array that can switch the resistance of selected cells back toward their initial resistance state to program the array in accordance with data received from a user or host device.
