Abstract: Methods, systems, and computer readable storage medium embodiments for hashing with improved utilization and power efficiency are disclosed. Some embodiments include inserting a key in a selected bucket in accordance with an bucket identifier generated by a hash function, wherein the selected bucket is one of a plurality of buckets of a hash table configured in at least one memory, determining respective unique bit strings based upon corresponding bit positions for a plurality of keys in the selected bucket including the inserted key, inserting the respective unique bit strings in a table location corresponding to the bucket identifier, wherein the table location is one of a plurality of table locations in at least one control table configured in the at least one memory. Other embodiments include lookup operations in a hash table.
