Abstract
A data reading/writing circuit includes a controller and a memory. The memory is configured to decode an instruction based on a first clock signal from the controller and to sample data based on a second clock signal from the controller. The memory includes first and second storage modules, and a mode register that stores a second synchronization parameter, and a second delay circuit is disposed in the second storage module. In reading/writing data on the first storage module, the controller is configured to synchronize the first and second clock signals using a first synchronization parameter. In reading/writing data on the second storage module, the controller is configured to perform first synchronization on the first and second clock signals using the first synchronization parameter, and the memory is configured to perform second synchronization on the first and second clock signals using the second delay circuit and the second synchronization parameter.
