A control method for a memory system is provided. A memory controller of the memory system is configured to control the memory device. After a condition is met, the memory controller performs a retry operation to compensate for shifting of a data strobe signal sent from the memory device until the memory system enters a normal operation mode. When the shifting of the data strobe signal is compensated for, the number of pulses of the data strobe signal in the gating window is equal to the first predetermined number.

Control methods and memory systems using the same

The first clock tree circuit includes a first driving stage for receiving the first signal, a second driving stage, connected to the first driving stage, a third driving stage, connected to the second driving stage, and a metal connection element, coupled between different nodes of the third driving stage and configured as a short-circuited element.

Clock tree circuit and memory controller

A clock tree circuit includes a clock source and a tree circuit. The clock source generates a signal. The tree circuit at least includes five driving units and a metal connection element. A first driving unit has an input terminal for receiving the signal, and an output terminal coupled to a first node. A second driving unit has an input terminal coupled to the first node, and an output terminal coupled to a second node. A third driving unit has an input terminal coupled to the first node, and an output terminal coupled to a third node. A fourth driving unit has an input terminal coupled to the second node. A fifth driving unit has an input terminal coupled to the third node. The metal connection element is coupled between the second node and the third node, and configured as a short-circuited element.
