Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C 119(a) to Korean Application No. 10-2010-0028717 filed with the Korean Intellectual Property Office on Mar. 30, 2010, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a semiconductor module including a module control circuit and a control method thereof. Background technique [0004] In general, a module is a constituent unit of a machine or an electronic device having each known characteristic and is a component group as an attachable / detachable functional unit. In particular, a module constitutes a part of a device, device or device in terms of hardware, and is an assembly formed by coupling parts of the device, device or device to each other. The module can be replaced with another spare part and the module can be tested for functionality. [0005] A semiconductor memory device may include a ...
