ABSTRACT:
The invention relates to a circuit for coupling volatile memories to a microprocessor or to a test tool having a test connector suitable for connection to a second complementary connector which is connected to the links between the memories and the microprocessor. The circuit is characterized in that the second connector (17) is mounted as a terminal connector on the links going to the memories (11, 12), and in that it further includes a third connector (18) mounted as a terminal connector on the links going to the microprocessor (13), together with a removable connection circuit (20) for providing connections between said second and third connectors. The invention is particularly suitable for a franking machine.
