Abstract:
A static random access memory (SRAM) bit cell and a related SRAM array are provided. In one aspect, an SRAM cell is configured to perform an XNOR function on a first input value and a second input value. In another aspect, a number of the SRAM cells can be employed to form an SRAM array for supporting deep neural network and machine learning applications. The SRAM cell is coupled to a word line(s) and an inverted word line(s) that collectively define the first input value. The SRAM cell causes a voltage and/or current difference between a bit line(s) and a complementary bit line(s) coupled to the SRAM cell. By customizing the SRAM cell to enable the XNOR function and forming a binary neural network based on the SRAM array, it is possible to effectively implement computing-in-memory (CIM) for deep neural network and machine learning applications.
