Abstract
A memory system includes a memory chip and a memory controller that controls the memory chip. In a write operation, the memory controller transfers a first timing signal synchronized with a first clock and first data synchronized with the first timing signal to the memory chip. In a read operation, the memory controller transfers a second timing signal synchronized with at least a second clock to the memory chip. The second clock has a frequency different from a frequency of the first clock. In the read operation, the memory chip generates a third timing signal synchronized with the second clock based on the second timing signal, and transfers the third timing signal and second data synchronized with the third timing signal to the memory controller.
