Uniform randomness for program-erase cycles using multi-bit inversion seeds

A system for improving a performance of a non-volatile memory, the system comprising:

• a firmware configured to generate, based on a number of program erase cycles of the non-volatile memory, an inversion seed for a page type of the non-volatile memory;
• a hardware controller configured to:
• generate a circular shift flip sequence based on the inversion seed and a flip sequence, and
• perform a bit-flipping operation on an input bit sequence based on the circular shift flip sequence to generate an intermediate bit sequence;
• and
• a memory controller configured to:
• process the intermediate bit sequence to generate an output bit sequence, and
• write the output bit sequence to a page in the non-volatile memory, wherein the page is of the page type.

A non-transitory computer-readable storage medium having instructions stored thereupon for improving a performance of a non-volatile memory, the instructions, when executed by a processor, cause the processor to perform operations comprising:

• generating, based on a number of program erase cycles of the non-volatile memory, an inversion seed for a page type of the non-volatile memory;
• generating a circular shift flip sequence based on the inversion seed and a flip sequence;
• performing a bit-flipping operation on an input bit sequence based on the circular shift flip sequence to generate an intermediate bit sequence;
• processing the intermediate bit sequence to generate an output bit sequence;
• and
• writing the output bit sequence to a page in the non-volatile memory, wherein the page is of the page type.
