SYSTEMS AND METHODS FOR PREVENTING DATA REMANENCE IN MEMORY SYSTEMS
Methods, circuits, and systems for preventing data remanence in memory systems are provided. Original data is stored in a first memory, which may be a static random access memory (SRAM). Data is additionally stored in a second memory. Data in the first memory is periodically inverted, preventing dat...

| description | Methods, circuits, and systems for preventing data remanence in memory systems are provided. Original data is stored in a first memory, which may be a static random access memory (SRAM). Data is additionally stored in a second memory. Data in the first memory is periodically inverted, preventing data remanence in the first memory. The data in the second memory is periodically inverted concurrently with the data in the first memory. The data in the second memory is used to keep track of the inversion state of the data in the first memory. The original data in the first memory can be reconstructed performing a logical exclusive-OR operation between the data in the first memory and the data in the second memory. |
