Assignee: SONY GROUP CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 7:
8. A multiply-accumulate device comprising:
a comparator configured to compare, with a threshold voltage, a voltage generated by an electric charge stored in a storage circuit, and to output an output signal at a timing at which the voltage exceeds the threshold voltage; and
a control circuit configured to reduce, based on a predetermined set value, a charging current provided to the storage circuit from a plurality of inputs connected to the storage circuit,
wherein the control circuit reduces the threshold voltage supplied to the comparator based on a value of the voltage of the storage circuit, and
the control circuit reduces the threshold voltage so that the threshold voltage becomes equal to or higher than a maximum value of a voltage of the storage circuit at a first time when the output signal is output from the comparator.
