Abstract
A storage system has a memory with memory cells that can store a non-power-of-two number of states. A map is used to distribute data bits in the memory. The map can be a modified version of a quadrature amplitude modulation (QAM) map. The mapping can be done by a controller in the storage system or by the memory die. Performing the mapping in the memory die can reduce data traffic between the controller and the memory die, which can provide an improvement to performance and power consumption.
