Abstract
Various examples are directed to systems and methods for managing a memory system. The memory system may generate a first encrypted physical address using a first clear physical address. The memory system may generate a first encrypted logical-to-physical (L2P) pointer indicating the first logical address and a first encrypted physical address. The memory system may send the first encrypted L2P pointer to a host device for storage at a host memory.
Claims20
A memory system comprising:
- a memory array;
- a controller, wherein the controller is programmed to perform operations comprising:
- generating a first encrypted physical address using a first clear physical address;
- generating a first encrypted logical-to-physical (L2P) pointer indicating the first encrypted physical address and a first logical address corresponding to the first clear physical address;
- and
- sending the first encrypted L2P pointer to a host device for storage at a host memory.
A method comprising:
- generating, by a memory system, a first encrypted physical address using a first clear physical address;
- generating, by the memory system, a first encrypted logical-to-physical (L2P) pointer indicating the first encrypted physical address and a first logical address corresponding to the first clear physical address;
- and
- sending, by the memory system, the first encrypted L2P pointer to a host device for storage at a host memory.
A non-transitory computer readable medium comprising instructions thereon that, when executed by a processor, cause the processor to perform operations comprising:
- generating a first encrypted physical address using a first clear physical address;
- generating a first encrypted logical-to-physical (L2P) pointer indicating a first logical address associated with the first clear physical address and the first encrypted physical address;
- and
- sending the first encrypted L2P pointer to a host device for storage at a host memory.
