1. A method of a memory device, comprising:
generating, by a controller of the memory device, a first hashed index by hashing a source index comprising a namespace identification (NSID) and a keytag with a first hash function;
generating, by the controller, a second hashed index by hashing the source index comprising the NSID and the keytag with a second hash function;
accessing, by the controller, a first storage address corresponding to the first hashed index or the second hashed index;
comparing, by the controller, a tag portion corresponding to the first storage address with the source index to identify whether a conflict exists; and
in response to identifying whether the conflict exists, obtaining, by the controller, information from the first storage address.
