Control circuit, control method, and semiconductor memory

Abstract

Provided are a control circuit, a control method, and a semiconductor memory. The control circuit includes a timing control module and a command control module. An output terminal of the timing control module is connected to an input terminal of the command control module. The timing control module is configured to receive a first clock signal, perform counting based on the first clock signal, generate an error check and scrub (ECS) flag signal, and send the ECS flag signal to the command control module. The ECS flag signal is in a valid state when a counting value meets a preset condition. The command control module is configured to receive the ECS flag signal, obtain a refresh command signal when the ECS flag signal is in the valid state, and generate an ECS command signal based on the refresh command signal.

Dependencies are inferred from the claim text.
