Abstract:
A method of storing data in a multi-level charge-trapping memory array is described. An incidence-of-occurrence (i.e., frequency) analysis is performed on data to be programmed to identify data words combining a high programming voltage with a high frequency of occurrence. Those words are reassigned in order to reduce programming time.
