Embodiment Construction

[0029] Hereinafter, an embodiment of a semiconductor device embodying the present invention will be described with reference to the drawings.

[0030] figure 1 It is a block diagram of a schematic configuration of the semiconductor device 10 of the present embodiment.

[0031] The semiconductor device 10 includes a reconfigurable circuit 11 , a power on boot circuit (hereinafter referred to as “boot circuit”) 12 , a nonvolatile memory 13 and a register 14 , and these are formed on the same chip.

[0032] The reconfigurable circuit 11 consists of a plurality of reconfigurable circuits 21 (refer to figure 2 )constitute. Therefore, the reconfigurable circuit 11 switches the circuit configuration according to the combinatorial logic set by each reconfigurable circuit 21 .

[0033] In the nonvolatile memory 13 , circuit operation setting data for setting the combinational logic of each reconfigurable unit 21 is written in advance according to the functions realized by the reco...

Abstract

A semiconductor device that is difficult to reverse engineer. The semiconductor device includes a reconfigurable circuit having a circuit configuration that is switchable in accordance with circuit operation setting data. A non-volatile memory stores the circuit operation setting data. A register receives the circuit operation setting data from the non-volatile memory and provides the circuit operation setting data to the reconfigurable circuit when the semiconductor device is activated. Since the circuit configuration of the reconfigurable circuit is determined by the circuit operation setting data, the operation of the reconfigurable circuit cannot be analyzed when a peeling analysis is conducted on the semiconductor device.

Description

technical field [0001] The present invention relates to a semiconductor device and an ID generating device. Background technique [0002] Generally, in a portable device such as a mobile phone, a battery pack including a storage battery for supplying electric power to the main body is mounted so as to be detachable from the main body. Thus, when the battery deteriorates, the portable device can be continued to be used only by replacing the battery pack. [0003] However, due to the excessive pursuit of cost reduction by manufacturers of such battery components, some products that cannot meet the quality requirements are often produced. When such a battery pack is used, there is a risk that the equipment cannot be used, or the main equipment may malfunction due to heat generation or the like. [0004] Therefore, conventionally, an identification signal has been used for authentication of external equipment such as a battery pack mounted on a main machine in order to identif...
