Abstract
A method of writing data is performed in a data storage device with a controller and a memory. The memory includes latches and multiple storage elements and is operative to store a first number of bits in each storage element according to a first mapping of sequences of bits to states of the storage elements. The method includes loading data bits into the latches within the memory and generating manipulated data bits in the latches by manipulating designated data bits in the latches using one or more logical operations. The method also includes storing sets of the manipulated data bits to respective storage elements of the group of storage elements according to the first mapping. The designated data bits correspond to states of the respective storage elements according to a second mapping of sequences of bits to states. The second mapping is different than the first mapping.
