摘要： A programmable resistive circuit using magnetoresistive memory elements incorporated into one or more programmable segments coupled together between first and second terminals. Each segment includes at least one magnetoresistive memory element and at least one control input to select its state. The resistive circuit further includes select logic coupled to the control inputs of each segment to achieve a programmed resistance. A source signal is applied to the resistive circuit to develop an output signal that is a combination of signals developed by each of the memory elements in the resistive circuit. Bypass logic or switch devices may be included to selectively bypass or remove one or more segments. Each segment may include any combination of series and parallel coupled memory elements. The programmable segments may form a successive configuration to enable programming of progressive resistive values. The progressive resistive values may be linear and the successive configuration may be binary. A programmable current source is achieved by providing a voltage source in which the current is a combination of current signals developed by each of the memory elements in the resistive circuit. A programmable voltage source is achieved by forming first and second resistive circuits on either side of a voltage junction terminal and by applying a voltage source across both resistive circuits. The total resistance across the resistive circuits may be kept constant for each of multiple programmable voltages.

The MRAM architecture (314) includes a MRAM circuit (318) formed on the substrate (301); and a MRAM cell (316) coupled to and formed above the MRAM circuit (318).

摘要： A programmable oscillator including a memory array of magnetoresistive memory elements, where the memory array is programmed to any one of multiple states based on one or more values and provides an output signal that controls a variable oscillator. The variable oscillator provides a frequency signal that corresponds to the output signal. The oscillator may be a voltage controlled oscillator (VCO) where the memory array is a voltage divider receiving a voltage reference signal and having a voltage junction that asserts a control voltage to the VCO. The voltage divider may include multiple voltage dividers, each including resistive circuits coupled on either side of the voltage junction and each programmed by a corresponding value. A frequency select register stores a frequency select value to program a frequency voltage divider. A trim select register stores a trim value to program a trim voltage divider. A frequency control block receives a reference clock and the frequency signal and generates an error value that programs a dither voltage divider. A portion of the memory array may be preprogrammed for calibration. The voltage reference signal may be provided to an analog to digital converter that programs a compensation resistive circuit in the memory array. Alternatively, the memory array is configured as a variable current source that provides an output current signal to a current controlled oscillator. The values are combined into a programmable register, where the collective value of the register programs the variable current source on a periodic basis.

摘要： A memory device, such an MRAM device, includes self-healing reference bits (104) associated with a set of array bits (102). The memory performs an error detection step (e.g., using an error-correction coding (ECC) algorithm, to detect the presence of a set of errors within the data bits. One of the reference bits (104) is toggled to a different state if an error count is greater than a predetermined threshold. If the set of errors remains unchanged when subsequently read, the reference bit (104) is toggled back to its original state.
