Abstract
A memory purge system destructively purges the memory circuits of a memory device. The system includes a power supply for supplying a selectable voltage and current. Switching circuits electrically connect the power supply to the memory circuits of the memory device. A controller selects a voltage and current supplied by the power supply and activates the switching circuit to apply the voltage and current to the memory circuits. The controller determines whether the memory circuits have been destroyed by monitoring current flow into the memory circuits.
Claims20
A memory purge system for purging a flash memory device, the memory purge system comprising:
- a switching circuit for electrically connecting a power supply to a memory circuit of the flash memory device;
- and
- a controller for selecting a first voltage and current supplied by said power supply and activating said switching circuit to apply the first voltage and current to the memory circuit in response to a condition.
A method for purging a flash memory device, the method comprising the steps of:
- selecting a voltage and current supplied by a power supply;
- and
- activating a switching circuit connecting the power supply to a memory circuit of the memory device to apply the selected voltage and current to the memory circuit,
- wherein the switching circuit is activated in response to a condition.
A system for purging a flash memory device, the system comprising:
- a converter configured to supply a first voltage and current;
- a switching circuit electrically coupled to the converter and the flash memory device, the switching circuit comprising a switch configured to electrically connect the converter to a memory circuit of the flash memory device;
- and
- a first controller configured to activate the switch to apply the first voltage and current of the converter to the memory circuit of the flash memory device to damage a transistor in the memory circuit of the flash memory device.
