Abstract
The present disclosure provides read-out circuits for crossbar circuits. A crossbar circuit may include a plurality of bit lines intersecting with a plurality of word lines and a plurality of cross-point devices. Each of the plurality of cross-point devices is connected to at least one of the plurality of word lines and at least one of the plurality of bit lines. The crossbar circuit may further include an output sensor that generates a digital output representative of a sum of currents flowing through one or more bit lines of the crossbar circuit. The output sensor includes a first transistor serially connected to a second transistor and an analog-to-digital converter configured to output the digital output. The read-out circuit is an open loop circuit. The read-out circuit may be selectively connected to one of the plurality of bit lines to perform a read operation.
