Method of operating integrated circuit and integrated circuit

Abstract

A method of operating an integrated circuit is provided, including writing data to each memory cell in a first array of memory cells, powering off the integrated circuit, powering on the integrated circuit, reading data from each memory cell in the first array of memory cells in response to powering on the integrated circuit, and determining whether to allow an authentication operation of the integrated circuit in response to reading data from each memory cell in the first memory cell array. An integrated circuit is also provided that includes a first array of memory cells.

Description

technical field [0001] Embodiments of the invention relate to methods of operating integrated circuits and integrated circuits. Background technique [0002] The semiconductor integrated circuit (IC) industry has produced a wide variety of digital devices to solve problems in many different fields. Some of these digital devices, such as memory macros, are configured to store data. As ICs become smaller and more complex, the resistance of the wires in these digital devices also changes, affecting the operating voltage of these digital devices and overall IC performance. Contents of the invention [0003] According to an aspect of an embodiment of the present invention, there is provided a method of operating an integrated circuit, the integrated circuit comprising a first memory cell array, the method comprising: writing to each memory cell in the first memory cell array entering data; powering down the integrated circuit; powering up the integrated circuit; reading data ...
