Abstract :
We introduce a test setup for the extraction of unique identifiers and random bits using DRAM. By utilizing standard 512 MByte DDR3 modules, 400 bit/s of random bits can be generated and unique identifiers are extracted. We show that DRAM can be used as a physically unclonable function. In contrast to SRAM-based PUF, DRAM PUF allow for repeated operations without disconnecting supply voltage while still remaining fully functional for normal storage operations.
