REMOVABLE CODE UNIT Russian patent published in 2013 - IPC G06K19/04 

FIELD: information technology.

SUBSTANCE: removable code unit has a control unit, first and second groups of outputs of which are respectively connected to the first and second groups of inputs of a memory unit, the group of inputs/outputs of which is connected to the group of inputs/outputs of the control unit, the input and first output of which are respectively connected to the first output and input of an interfacing unit, the second input and output of which are connected to the first input and output of a connector; there is a filter and a programming unit, the group of outputs of which is connected to the group of inputs of the control unit, the second output of which is connected to the input of the programming unit, the group of inputs and output of which are connected to the group of outputs and the second input of the connector, the third output of which is connected to the input of the filter, the group of inputs; fourth and fifth outputs of the connector are the group of inputs and the first and second outputs of the device.

EFFECT: high reliability and service life of the removable code unit by reducing the number of discrete elements and including a filter which increases noise-immunity of the device.
