Original Abstract Submitted

Provided are a column control circuit and a memory device. The column control circuit includes a delay control circuit and a control signal generation circuit. The delay control circuit receives a column selection start signal, and generates and outputs a column selection end signal. The column selection end signal has a first delay amount relative to the column selection start signal. The control signal generation circuit receives the column selection start signal, the column selection end signal, and a target bank group selection signal, and generates and outputs a target column selection start signal, a target column selection window signal, and a target column selection end signal. The target column selection window signal has a second delay amount relative to the column selection start signal, the second delay amount is less than or equal to the first delay amount.
