Integrated circuit with a lead for fixing one of several forms of organization and method for its operation (for example, an integrated circuit memory)

摘要

An integrated circuit is in at least three different forms of organization (x4, x8, can be operated x16) which can be set externally. A connection path (p) is externally for fixing one of the forms of organization actuatable. An input of a control circuit (2) for setting one of the forms of organization is connected with the pad. As a function of the wiring of the connection pads (p) are of the control circuit (2) at least three different states for the identification of the respective organisational forms at the output can be generated. According to the reading out of the signal state and the activation of the corresponding form of organisation, the control circuit (2) of a voltage supply of the integrated circuit (1) is switched off. The circuit according to the invention, the number of connection pads for fixing the form of organisation be kept small.
