COMPUTE-IN-MEMORY DEVICES AND METHODS OF OPERATING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17827223 titled 'COMPUTE-IN-MEMORY DEVICES AND METHODS OF OPERATING THE SAME

Simplified Explanation

The abstract describes an integrated circuit that includes a logic gate and a backup storage component. The logic gate receives two input signals and generates a control signal based on the bits of the input signals. The backup storage component stores the bits of the input signals obtained in the previous cycle. The circuit also includes multiple macros that compute a multiply-accumulate value based on the control signal.

• The integrated circuit includes a logic gate that processes two input signals and generates a control signal.

Original Abstract Submitted

An integrated circuit includes a first logic gate configured to receive a first input signal and a second input signal, and generate a first control signal based on a first bit of first input signal and a first bit of the second input signal obtained in a current cycle. The integrated circuit includes a first backup storage component configured to store a second bit of the first input signal and a second bit of the second input signal obtained in a previous cycle. The integrated circuit includes a plurality of first macros each configured to selectively compute, based on the first control signal, a first multiply-accumulate (MAC) value for the first bit of the first input signal and the first bit of the second input signal.
