  • Publication number: 20070274125
    Abstract: A nonvolatile memory cell includes a bipolar programmable storage element operative to store a logic state of the memory cell, and a metal-oxide-semiconductor device including first and second source/drains and a gate. A first terminal of the bipolar programmable storage element is adapted for connection to a first bit line. The first source/drain is connected to a second terminal of the bipolar programmable storage element, the second source/drain is adapted for connection to a second bit line, and the gate is adapted for connection to a word line.

  • Publication number: 20070247893
    Abstract: A nonvolatile memory array includes a plurality of word lines, a plurality of bit lines, a plurality of source lines, and a plurality of nonvolatile memory cells. Each of at least a subset of the plurality of memory cells has a first terminal connected to one of the plurality of word lines, a second terminal connected to one of the plurality of bit lines, and a third terminal connected to one of the plurality of source lines. At least one of the memory cells includes a bipolar programmable storage element operative to store a logic state of the memory cell, a first terminal of the bipolar programmable storage element connecting to one of a corresponding first one of the bit lines and a corresponding first one of the source lines, and a metal-oxide-semiconductor device including first and second source/drains and a gate.

  • Publication number: 20060187803
    Abstract: A storage device including a storage medium for storing data in the form of topographic or magnetic marks. At least one probe is mounted on a common frame, the common frame and the storage medium designed for moving relative to each other for creating or detecting said marks. Each probe includes a tip facing the storage medium, a read sensing element, a write element and a capacitive platform, that forms a first electrode and is designed for a voltage potential applied to it independent from a control signal for said read sensing element and for said voltage potential applied to said capacitive platform being independent from a control signal for said write heating element. It further comprises a second electrode arranged in a fixed position relative to the storage medium forming a first capacitor together wherein said first electrode and a medium between the first and second electrode.

  • Publication number: 20060071272
    Abstract: A memory element comprises a first number of electrodes and a second number of electrically conducting channels between sub-groups of two of said electrodes, the channels exhibiting an electrical resistance that is reversibly switchable between different states, wherein the first number is larger than two and the second number is larger than the first number divided by two. The electrically conducting channels may be provided in transition metal oxide material, which exhibits a reversibly switchable resistance that is attributed to a switching phenomenon at the interfaces between the electrodes and the transition metal oxide material.

  • Publication number: 20050260839
    Abstract: Processes, apparatus and systems for depositing a switching material that is switchable between conductivity states and where the states are persistent. The invention further relates to a microelectronic device or non-volatile resistance switching memory comprising the switching material for storing digital information. A process includes a step of depositing the switching material by a CMOS deposition technique at a temperature lower than 400° C.
