DATA STORAGE BASED ON RANK MODULATION IN SINGLE-LEVEL FLASH MEMORY

摘要

Technologies are generally described to store data in single-level memory using rank modulation. In some examples, data to be encoded to single-level memory may be represented with a bit ranking for a group of bits. A program vector may then be determined from the bit ranking and partial program characteristics associated with the memory group(s). The memory group(s) may then be programmed according to the program vector. The encoded data may be subsequently retrieved by performing a series of partial programming operations on the memory group(s) to recover the bit ranking and derive the data represented.

1. A method to encode data on single-level flash memory by use of rank modulation, the method comprising:
determining a bit ranking within a group of bits based on the data to be encoded; determining a plurality of partial program parameters for a plurality of flash memory bits, wherein each partial program parameter is associated with a respective bit in the plurality of bits; determining a program vector based on the determined bit ranking and the determined plurality of partial program parameters; and encoding the data to the plurality of bits using partial programming based on the determined program vector.
