Abstract: Techniques for data manipulation based on local differential privacy using static random-access memory are disclosed. Data that requires differential privacy data manipulation is accessed for storage. The data is prepared for storage using key-based shuffling. Keys are selected by a random key index generator. The shuffled data is stored in a static random-access memory (SRAM). The SRAM comprises high-reliability and low-reliability storage cells. A supply voltage of the SRAM is lowered. The lowering a supply voltage produces a pre-characterized noise level in the SRAM storage cells. Cells among the low-reliability cells are flipped based on the pre-characterized noise level. The flipping cells are used to inject random noise, and their values are provided by random noise generators. A read of the stored data is performed. The read occurs across both high-reliability and low-reliability storage cells. The data that was read is unshuffled, using key-based unshuffling.
