decrypt embedded microcontroller eeprom memory, as we mentioned above, embedded microcontroller decrypter can use laser scanning to read the status of transistors. And just embedded microcontroller decrypter expected, laser can scan the P and N type transistor’s source in the embedded microcontroller memorizer as well as the photocurrent generated from the drain electrode, un-transparent metal wire can be use to treat the lowest photocurrent.
The result of laser scanning can see the photocurrent in the inverse switch status of SRAM unit obviously whembedded microcontrollerh can be used to assure the embedded microcontroller memorizer status after decrypting it. In order to explain the result for the purpose of pursuit more proper scanning parameters, use DIODE-2D present the laser impulse to two dimension of reversor after Decrypt Embedded Microcontroller Eeprom Memory.
The length of narrow channel is assumed to be 1 micron, laser radiation strength is 1.104W/cm2. Other parameters, such as mixed density, P and N channel depth, use the standard 1 micron N type base CMOS technology parameter of embedded microcontroller.
Embedded microcontroller decrypter has simulate the two status of reversor, the laser with different wavelength on the various locations, their relationship with the power supply current can reveal that the current of transistor in the turn off exposure status could be much bigger than the current in the turn on exposure status when Decrypt Embedded Microcontroller Eeprom Memory. Turn up the shutdown transistor channel can increase the total current and its increasing amount is much bigger than the slightly decrease the open channel resistor slight.
