Abstract
Methods and apparatus related to generating random numbers utilizing the entropic nature of NAND flash memory medium are described. In one embodiment, a data pattern is written to a portion of a non-volatile memory device and is subsequently read multiple times. Based on the read operations, at least one bit is marked for random number generation based at least partially on comparison of a number of flips by the at least one bit and a threshold value. Other embodiments are also disclosed and claimed.
