Memory device and method for computing-in-memory (cim)

A memory device, comprising:

• a memory array comprising at least one memory segment configured to store weight data;
• at least one weight buffer coupled to the at least one memory segment, and configured to hold new weight data to be updated in the at least one memory segment;
• at least one logic circuit having
• a first input coupled to the at least one memory segment by at least one bit line,
• a second input configured to receive input data, and
• an output;
• and
• a computation circuit coupled to the output of the at least one logic circuit,
• wherein
• the at least one logic circuit is configured to generate, at the output, intermediate data corresponding to the input data and the weight data read from the at least one memory segment through the at least one bit line, and
• the computation circuit is configured to, based on the intermediate data, generate output data corresponding to a computation performed on the input data and the weight data read from the at least one memory segment.
