System and method for improving error distribution in multi-level memory cells
Abstract:
A system including a state set module to arrange states of a memory cell in three sets. The memory cell stores three bits when programmed to a state. Each set includes three rows of bits. In a set, a row includes one of the three bits of the states. The first, second, and third rows of the first, second, and third sets include a first number of state transitions. The second, third, and first rows of the first, second, and third sets include a second number of state transitions. The third, first, and second rows of the first, second, and third sets include a third number of state transitions. A write module writes first, second, and third portions of data to a plurality of memory cells, each memory cell storing the three bits when programmed to a state, using states selected respectively from the first, second, and third sets.
