Abstract
The present disclosure relates to voltage-mode crossbar circuits that may include a plurality of bit lines intersecting with a plurality of word lines, a plurality of cross-point devices, and a plurality of sensing circuits configured to amplify bit line voltages settled on the bit lines in response to an application of input voltages to the cross-point devices via the word lines and generate digital outputs representative of the amplified bit line voltages. Each cross-point device is connected to one of the word lines and one of the bit lines and may include a resistive random-access memory (RRAM) device. Each cross-point device may further be connected to a local select line that may enable a group of cross-point devices connected to one or more bit lines. A cross-point device may be enabled when both a global select line and the local select line connected to the cross-point device are enabled.
