Abstract
The data management method applies to a multilevel nonvolatile memory device having a memory array formed by a plurality of memory cells. Each of the memory cells stores a number of bits that is not an integer power of two, for example three. In this way, one data byte is stored in a non-integer number of memory cells. The managing method includes storing, in a same clock cycle, a data word formed by a plurality of bytes, by programming a preset number of adjacent memory cells. Reading is performed by reading, in a same clock cycle, the stored data word.
