Abstract
Disclosed herein is an apparatus for hardware metering using a memory-type camouflaged cell. The apparatus includes memory including at least one camouflaged memory cell in which a key is hidden by a designer in advance and a controller for controlling whether to block the supply of power to the memory. The controller may perform reading a key from a corresponding key location in the multiple memory cells of the memory based on key location information stored in the controller when a key is input from the outside, determining whether the key input from the outside is the same as the key read from the memory, setting an authentic flag based on the determination result, and performing control based on the set authentic flag such that the memory operates normally or the supply of power is blocked.
