NONVOLATILE MEMORY DEVICE AND NONVOLATILE MEMORY SYSTEM AND RANDOM DATA READ METHOD THEREOF |
摘要 |
A random data reading method of a nonvolatile memory device includes receiving an initial seed corresponding to a selected page of the nonvolatile memory device and relative location information of read-requested random data in the selected page. The method further includes generating a seed for randomizing the random data by subjecting the initial seed and the location information to a finite field arithmetic operation, and de-randomizing the random data based on a random sequence generated from the seed. |

1. A method of reading data in a nonvolatile memory system that comprises a plurality of pages including a first page, the first page including a plurality of sectors, the plurality of sectors including a first sector and a second sector, an address of the first sector preceding an address of the second sector, the method comprising:
receiving a read request for reading data in the second sector, the read request including a page address corresponding to the first page and a sector address corresponding to the second sector; generating a first seed based on the page address; generating a second seed based on the first seed and on the sector address; generating a second random sequence corresponding to the data in the second sector based on the second seed; and generating output data based on the second random sequence and on the data in the second sector, wherein a first random sequence corresponding to data in the first sector is not generated in response to the read request for reading the data in the second sector. |
