Abstract
A data read/write system receives a key associated with a data read request. The data read/write system hashes the key to obtain a first hash value and hashes the key to obtain a second hash value, where the second hash value is different than the first hash value. The data read/write system obtains a pointer from a pointer array using the first and second hash values, and uses one or more bits of the pointer and the first hash value to retrieve data from a data look-up array.
