Abstract
A memory system includes memory chips connected to each other. Each of the memory chips includes a memory array, a read/write data strobe pin, a look-up table storage device, a chip number identification circuit, and a control logic circuit. The memory array stores data. The read/write data strobe pin is connected to read/write data strobe pins of other memory chips. The look-up table storage device stores a plurality of trimming shift values related to a number of chip connections in advance. The chip number identification circuit identifies a current number of chip connections according to a state information, and finds a selected trimming shift value from the look-up table storage device. The control logic circuit transmits a data signal in response to a clock signal, and adjusts a setup hold time between the clock signal and the data signal according to the selected trimming shift value.
