US Patent 10884944 Host accelerated operations in managed NAND devices

Devices and techniques for host accelerated operations in managed NAND devices are described herein. A controller can receive an operation. Here the operation includes address data with a logical address portion and a physical address portion. The controller can then extract an index value and a location value from the physical address portion. The controller can retrieve a key using the index value and invoke a reversible function—using the index value and the location value—to produce a physical address. The controller can then perform the operation using the physical address.
