  • Mixed-signal interface circuit for non-volatile memory crossbar array
    Patent number: 11942148
    Abstract: Crossbar arrays perform analog vector-matrix multiplication naturally and provide a building block for modern computing systems. Specialized mixed-signal interface circuits are interfaced with the rows and columns of the crossbar arrays. During operation, the mixed-signal interface circuits provide high voltages for write operations and low voltages for read operations. This disclosure presents improved designs for the mixed-signal interface circuits which minimize the number of switches as well as the number level shifters.

  • One-Transistor Processing Element For Non-Volatile Memory Crossbar Array
    Publication number: 20220342635
    Abstract: Crossbar arrays perform analog vector-matrix multiplication naturally and provide a building block for modern computing systems. In many applications, the weights stored in the crossbar array are learned off-line and then stored on embedded devices. After the weights are learned, they do not change. Since the weights do not change in these applications, this disclosure envisions a new implementation for the processing elements of the crossbar array.
