1. A data processing system, the system comprising:
a solid state memory; a data de-randomizer circuit operable to de-randomize a read data set accessed from the solid state memory device; a soft data generation circuit operable to:
receive multiple instances of one or more elements the read data set, wherein each instance of a respective element is read using a different reference value;access a scramble compensating extended look up table using the multiple instances of the element to receive corresponding soft data; and a data decoder circuit operable to apply a soft decoding algorithm to the soft data to yield a decoded output.
