Multi-channel semiconductor integrated circuit devices for controlling direct current generators and memory systems including the same

A multi-channel semiconductor integrated circuit device comprising:

• a plurality of memory devices that are independently accessible, each of the plurality of memory devices comprising at least one power generation unit;
• and
• a detection unit for detecting an operation state of the plurality of memory devices,
• wherein the at least one power generation unit of the plurality of memory devices configured to be independently controlled for each of the plurality of memory devices by a dedicated control unit or commonly controlled for the plurality of memory devices by a common control unit, separate and distinction from the dedicated control unit, according to a control mode determined by the operation state of the plurality of memory devices detected by the detection unit.

A memory system comprising:

• a multi-channel semiconductor integrated circuit device comprising a plurality of memory devices, each comprising at least one power generation unit, and a detection unit for detecting an operation state of the plurality of memory devices;
• a controller configured to control the multi-channel semiconductor integrated circuit device;
• and
• a plurality of channels, each independently interfacing a corresponding one of the plurality of memory devices and the controller,
• wherein the at least one power generation unit of the plurality of memory devices is commonly controlled in a common control mode by a common control unit and individually controlled for each of the plurality of memory devices by a dedicated control unit, separate and distinct from the common control unit, according to an operation state of the corresponding memory device in an individual control mode, and the individual control mode and the common control mode are determined according to the operation state of the plurality of memory devices detected by the detection unit.
