Techniques are described herein for storing and processing codes included in dictionary-encoded data. In an embodiment, for each respective code of a plurality of codes in the dictionary-encoded data: a plurality of bits from a first portion of the respective code is contiguously stored. One or more bits from a second portion of the respective code is stored in one or more slices. Each respective slice of the one or more slices stores a bit from the one or more bits with a corresponding bit position in the respective code. In another embodiment, a bit-vector is generated based on at least one slice by loading each respective bit of the plurality of bits into different respective partitions in a register at a bit position corresponding to the at least one slice. A plurality of codes may be reconstructed by combining the bit-vector with one or more other bit-vectors
