Abstract: Example embodiments for descrambling and scrambling a memory channel comprise: executing a training mode for the memory device to discover XOR vectors used by the host system to scramble data by: inputting all zero training data to a scrambling algorithm for all memory locations of the memory device to generate scrambled training data that is transmitted over the memory channel to the memory device, such that the scrambled training data are equal to the XOR vectors corresponding to those memory locations; receiving the scrambled training data over memory channel by the memory device and storing the scrambled training data as the XOR vectors for each of the corresponding memory locations; and during a functional mode of the memory device, receiving the scrambled data over the memory channel for a specified memory location, and using the XOR vector stored for the specified memory location to descramble the scrambled data prior to writing to the specified memory location.

Abstract: Example embodiments for descrambling and scrambling a memory channel include executing a training mode for the memory device to discover XOR vectors used by the host system to scramble data. The training mode inputs all zero training data to a scrambling algorithm for all memory locations of the memory device to generate scrambled training data that is transmitted over the memory channel to the memory device. The scrambled training data are equal to the XOR vectors corresponding to those memory locations. The scrambled training data is received over the memory channel by the memory device and stored as the XOR vectors for each corresponding memory location. During a functional mode, the scrambled data is received over the memory channel for a specified memory location and the XOR vector stored for the specified memory location is used to descramble the scrambled data prior to writing to the specified memory location.
