Logical address translation

摘要

The present disclosure includes methods for logical address translation, methods for operating memory systems, and memory systems. One such method includes receiving a command associated with a LA, wherein the LA is in a particular range of LAs and translating the LA to a physical location in memory using an offset corresponding to a number of physical locations skipped when writing data associated with a range of LAs other than the particular range.

主权项

1. A method for logical address (LA) translation, comprising:
associating a first encryption key with a particular range of LAs and a second encryption key with a range of LAs outside the particular range, performing a write operation that includes skipping a number of physical locations corresponding to an offset such that data associated with the particular range of LAs is on a different page than data associated with the range of LAs outside of the particular range in response to the write operation including data associated with the first encryption key and data associated with the second encryption key; and translating the LA to a particular physical location in memory within the number of physical locations using the offset.
