Abstract

See full text

A multi-bit cell includes: a memory storing a weight resistance corresponding to a multi-bit weight; a current source configured to apply a current to the memory to generate a weight voltage from the weight resistance; a plurality of multiplexers connected to each other in parallel and connected to the memory in series, each of the multiplexers being configured to output one signal of the weight voltage and a first fixed voltage based on a multi-bit input; and a plurality of capacitors connected to the plurality of multiplexers, respectively, each of the capacitors being configured to store a respective weight capacitance, and to generate charge data by performing an operation on the outputted signal and the weight capacitance.
