FIELD: physics, computer engineering.
SUBSTANCE: invention relates to computer engineering, particularly to means of protecting information from unauthorised access. The data storage device has a control unit, the first group of inputs/outputs of which is connected to the group of inputs/outputs of a memory unit, the device further including a commutation unit for switch circuits and a unit for protecting switch circuits, the group of inputs of which is the group of inputs of the data storage device, and the group of outputs is connected to the group of inputs of the commutation unit for switch circuits, the first group of inputs/outputs of which is the group of inputs/outputs of the data storage device, and the second group of inputs/outputs is connected to the second group of inputs/outputs of the control unit.
EFFECT: high reliability of the data storage device and providing high security of information storage.
