Abstract
A programmable crossbar array with inline fuses includes a layer of row lines and a layer of column lines with the row lines crossing over the column lines to form junctions and resistive memory elements sandwiched between row lines and a column lines at the junctions. Inline fuses are located in either the row lines, column lines or both. The inline fuses are interposed between the support circuitry and the resistive memory elements. A method for mitigating shorts in a crossbar array is also provided.
Claims20
A programmable crossbar array with inline fuses comprising:
- a layer of row lines;
- a layer of column lines, the row lines crossing over the column lines to form junctions;
- resistive memory elements sandwiched between row lines and column lines at the junctions;
- support circuitry;
- and
- inline fuses in either the row lines, column lines or both, the inline fuses interposed between the support circuitry and the resistive memory elements.
A method comprising:
- detecting a shorted memristor in a crossbar array, in which the shorted memristor is connected to a row line and column line;
- and
- blowing a fuse inline with one of the row line or the column line.
