Abstract
A circuit includes a delay generation circuit. The delay generation circuit is configured to generate a sub-grab signal for each of the storage areas based on an initial grab signal and data transmission delay of each of the storage areas, and generate a grab enable signal based on all the sub-grab signals. A time interval between a time when the read-write control circuit receives data transmitted from each of the storage areas by a global data line and a time when the read-write control circuit receives the sub-grab signal corresponding to the storage area satisfies a preset range. The read-write control circuit is configured to read out data of the global data line to a data bus based on the grab enable signal. Therefore, the tCCD of the DRAM is optimized.
