The central concept behind Apacer SLC-Lite is to make MLC behave like SLC. To achieve SLC-like performance and endurance, cell distribution management for MLC is necessary in order to greatly adjust the voltage delta and charge sensing. MLC flash can program its cell into 4 different pairs of bits – 11, 01, 00, and 10. By only programming the least significant bit (LSB) of the MLC flash – 11 and 10, SLC-Lite behaves almost identical to that of SLC flash. This highly improves the precision of delta and the threshold voltage of each cell. Thus, the MLC performance and endurance, especially in P/E cycles, will be escalating by multiples to the level almost on par with SLC. In this case, users would get all the benefits of both the quality and the cost.
