The system utilized a "Loader" hierarchy. was the grandmaster key holder. If code was signed by Sony’s private key, Metldr would verify it and load it into a protected Synergistic Processing Unit (SPU) isolation mode, invisible even to the main PowerPC (PPU) core.

The PS3 memory management utilized a bus interface. Hotz utilized a method known as "glitching." By physically manipulating the voltage or clock speed of the bus (using an FPGA or simple logic analyzer), he could disrupt the communication between the CPU and memory during a critical verification step. ps3exploit
