摘要:
A storage device includes a probe having a tip, the tip comprising a first portion and a second portion. The storage device also includes a storage medium having a surface, where the tip of the probe is adapted to form a dent in the storage medium. The second portion of the tip is electrically contacted to the surface of the storage medium in response to the tip being engaged in the dent, and the second portion of the tip is spaced apart from the surface of the storage medium in response to the first portion being engaged on the surface of the storage medium and not engaged in the dent.

A storage device includes a probe having plural tips, and a storage medium having a surface. At least a first one of the tips is adapted to form a dent in the storage medium, and at least a second one of the tips is adapted to be electrically contact the surface of the storage medium in response to the first tip being engaged in the dent. The second tip is electrically isolated from the storage medium in response to the first tip being engaged on the surface of the storage medium and not being engaged in the dent.

A storage device includes an electrically conductive storage medium and a probe having a tip that is electrically conductive. The tip is electrically contacted to the storage medium and is adapted to form a dent in the storage medium. The tip is also adapted to cooperate with the storage medium to provide a variable resistance based on whether the tip is engaged in the dent.

A storage device includes a storage medium and a probe having a tip and a first plate. The tip of the probe is adapted to form a dent in the storage medium to represent a state of a data bit. The storage device also includes a second plate, where the first plate and second plate cooperate to form a variable capacitance that varies between different capacitance values depending on whether the tip of the probe is engaged in the dent.
摘要:
A read-only memory device is described having non-volatile memory cells that include a memory component connected between electrically conductive traces. A memory component is formed to include a resistor that indicates a resistance value when a potential is applied to a selected memory cell. The resistance value of a memory component in an individual memory cell corresponds to multiple logical bits. The resistance value of a memory component corresponding to a set of logical bits can be based on a thickness and/or an area of electrically resistive material that forms the memory component, and/or based on the geometric shape of the memory component, where different geometric shapes of the electrically resistive material have different resistance values that correspond to different sets of logical bits.

Exemplar embodiments are disclosed which allow errors in a magnetoresistive solid-state storage device, such as a magnetic random access memory (MRAM) device, to be minimized. An illustrative method includes the steps of identifying cells in the device which have a failure mode characterized by a propensity to remain in a particular orientation of magnetization, mapping the location of the identified cells, and compensating for the failure mode of a cell at a mapped location. Systems and computer readable media are also provided.

Systems and methods for reducing the effect of noise while reading data from memory, are provided. One system embodiment includes a memory cell that stores a first data; multiple sensing devices that receive the first data and provide a first set of outputs; and a voting system that evaluates the first set of outputs to determine whether one of the outputs of the first set is valid data from the memory cell. One method embodiment includes reading data in parallel that is stored in a memory cell to provide outputs; and evaluating the outputs to determine whether one of the outputs is valid data from the memory cell.

Methods for storing a bit sequence are provided. A representative method for storing a bit sequence includes converting a first bit sequence containing a first number of low-resistance bits into a second bit sequence containing a second number of low-resistance bits that is lower than the first number of low-resistance bits, and then storing the second bit sequence in a resistance-based memory device. Systems, computer-readable media, and other methods for storing and retrieving a bit sequence are also provided.
