Microcontroller

One of the key drivers to increase capacity in next generation storage has been to increase the number of bits that can be stored per cell. The easy jump of one to two bits-per-cell gives a straight 100% increase, in exchange for more control needed to read/write the bit but also limits the cell endurance. We’ve seen commercialization of storage up to four bits-per-cell, and talk about five. A Japanese company is now ready to start talking about their new 7 bits-per-cell solution.

As more bits are added, the value of adding those bits diminishes, but...
