Abstract: A method of encoding/decoding data for storage in and retrieval from a flash memory device, can be provided by generating a first error correction code on a combination of first user data to be stored in a first logical unit of storage in the flash memory device and padding data that is derived from second user data and an associated second error correction code stored in a second logical unit of storage in the flash memory device that is directly adjacent to the first logical unit of storage. The first user data and the first error correction code can be stored in the first logical unit of storage.

Abstract: A semiconductor memory device is provided. The semiconductor memory device includes an error correction code block and a memory. The error correction code block performs error correction encoding for user data to generate parity data. The memory stores the user data and the parity data. The error correction code block generates parity data, including a number of bits equal to at least 2t, wherein t is a natural number, and the bits of the parity data distinguish free page data from user data that is equal to the free page data.
