摘要： In a method of programming a magneto resistive memory cell, a first magnetic field is applied to the magneto resistive memory cell. It is determined whether the magneto resistive memory cell meets a programming criterion. In case that the magneto resistive memory cell does not meet the programming criterion, a second magnetic field, which is higher or lower than the first magnetic field, is applied to the magneto resistive memory cell. It is then determined whether the magneto resistive memory cell meets a programming criterion. The magnetic field is increased or decreased in case that the magneto resistive memory cell does not meet the programming criterion until the magneto resistive memory cell meets the programming criterion.

摘要： A method for controlling the constant power dissipation of a memory cell includes initially measuring the resistance of the memory cell, and subsequently controlling a source to apply a variable level of current or voltage to the memory cell. The variable level of the applied current or voltage is determined in proportion to the measured resistance of the memory cell so as to result in a predefined level of power dissipation within the memory cell, said dissipated power operable to heat the memory cell.

摘要： A symmetrical high-speed current sense amplifier having complementary reference cells and configurable load devices that eliminates architecture-related capacitive mismatch contributions. The current sense amplifier is adapted for use in a symmetric sensing architecture and includes a configurable load device. The current sense amplifier includes a voltage comparator, a first clamping device coupled between a first input of the voltage comparator and a first input signal, the first clamping device being coupled to a reference voltage. A second clamping device is coupled between the second input of the voltage comparator and a second input signal, the second clamping device being coupled to the reference voltage. The load device may comprise a current mirror that is coupled between the first and second input of the voltage comparator. The current mirror may be configurable by select transistors. Alternatively, the load device may be a hard-wired current mirror, and a multiplexer may be used to select whether the first input signal or the second input signal is connected to a first or second side of the current mirror. Configurable dummy loads may be added at appropriate nodes to optimize the capacitive load and increase the speed of the amplifier. Equalization devices may be coupled between the first and second inputs of the voltage comparator, and between the first input signal and the second input signal.
