摘要： A synchronous semiconductor memory device has a read data bus for transferring data from a memory cell array to a read amplifier, and a write data bus for transferring data from a write driver to the memory cell array. To control equalization of the read and write data buses, an internal control clock signal is driven to a first level in delayed synchronization with an external clock signal, to a second level in synchronization with the external clock signal at the end of write operations, and to the second level in synchronization with a read amplifier control signal during read operations. The read and write data bus equalization times can therefore be separately optimized, enabling the memory to operate at a higher clock frequency than if the internal control clock signal were to be generated in the same way during both read and write operations.
