Abstract:
Systems and method relating generally to solid state memory, and more particularly to systems and methods for generated data from a solid state memory. A data processing system includes 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 and 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. Each instance of a respective element may be read using a different reference value.
