DESCRAMBLING OF SCRAMBLED LINEAR CODEWORDS USING NON-LINEAR SCRAMBLERS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18419846 titled 'DESCRAMBLING OF SCRAMBLED LINEAR CODEWORDS USING NON-LINEAR SCRAMBLERS

Simplified Explanation

The memory device described in the patent application is designed to descramble scrambled composite data by performing an XOR operation with scramble codes generated by non-linear scramblers. This process removes the scrambling from the composite data, which may consist of multiple data sets scrambled with non-linear scramblers. The scrambled data sets are typically data to be written to a NAND device at high bit per cell densities, such as MLC, TLC, QLC, PLC, etc. The memory device can be used to read the scrambled data sets that have been written in a previous programming pass.

Original Abstract Submitted

A memory device configured to descramble scrambled composite data. In one approach, the scrambled composite data is provided by an XOR (exclusive OR operation) of more than one data set scrambled with non-linear scramblers. A memory device is configured to receive scramble codes generated by non-linear scramblers and perform an XOR of the scrambled composite data with the scramble codes to remove scrambling from the composite data. In one example, the scrambled data sets are data to be written to a NAND device at more than one bit per cell density (e.g., MLC, TLC, QLC, PLC, etc.). For example, the scrambled data sets may be written to the NAND device in more than one programming pass. In one example, the scrambled composite data is used to read the scrambled data sets that have been written in a first programming pass.
