Single-level Cell

Show Index


SLC (single-level cell) is one type of memory cell that is used in flash memory. In a SLC, data is stored as one bit per memory cell. Since data is recorded by setting voltage at either of two levels only ("high" or "low"), the effect of noise is hardly incurred. As a result, a SLC operates quicker than a MLC (multi-level cell), and its reliability is higher. Its cost per byte (capacity) is, however, high.
