Semiconductor module including module control circuit and method for controlling the same

摘要

A module control circuit includes an input unit configured to receive a plurality of data signals from a plurality of data input/output pins and output an identification signal and an internal command signal. A latch unit is configured to latch the identification signal in accordance with a first enable signal to output a first group identification signal, latch the identification signal in accordance with a second enable signal to output a second group identification signal, and latch the internal command signal in accordance with the second enable signal to output a group command signal. A comparator is configured to compare the first group identification signal with the second group identification signal, and generate a selection signal. A multiplexer is configured to select one of the group command signal and a module command signal as an input command in response to the selection signal.
