Abstract
A memory processing system according to the embodiment includes a system controller and a plurality of memory modules. The controller and the memory module transmit data from each other employing a data transmission line which is terminated only at an end at the side of the memory module. The memory chip monitors a reflected wave obtained at the time of data output to the data transmission line, thereby measuring the length of the data transmission line. Based on the measurement result, the system controller determines set up time/hold time for each memory chip.
