Non-Volatile Memory Randomized Power Access Against Data Theft

The patent changes the power consumption parameter by introducing random power values generated from a random number. The power supply unit provides different power consumption levels (first power consumption and second power consumption) based on the random number, making the power consumption pattern unpredictable and preventing attackers from exploiting consistent power patterns to infer stored data.

The patent introduces dynamic behavior by randomly selecting between different power consumption modes during data access operations. The memory access controller generates random numbers to determine whether to use first or second power consumption when reading data, creating a dynamic and unpredictable power consumption pattern that prevents static analysis attacks.

The patent implements multi-functionality by having the random number generator serve multiple purposes: it generates random numbers for power consumption control, for access sequence generation, and for data reconstruction. This single component performs multiple security-related functions, reducing the need for separate dedicated components and thereby limiting the increase in device complexity.

The patent introduces a memory waveform generator as an intermediary component that bridges the random number and the memory access controller. This intermediary translates random numbers into appropriate access sequences and power control signals, managing the complexity by providing a dedicated translation layer rather than requiring direct complex interactions between all components.
