Internal ECC enables 5-bit detection and 4-bit error correction in 512 bytes (x8) or 256
words (x16) of the main area and 4 bytes (x8) or 2 words (x16) of metadata I in the spare
area. The metadata II area, which consists of two bytes (x8) and one word (x16), is not
ECC protected. During the busy time for PROGRAM operations, internal ECC generates
parity bits when error detection is complete.
During READ operations the device executes the internal ECC engine (5-bit detection
and 4-bit error correction). When the READ operaton is complete, read status bit 0
must be checked to determine whether errors larger than four bits have occurred.
Following the READ STATUS command, the device must be returned to read mode by
issuing the 00h command.
Limitations of internal ECC include the spare area, defined in the figures below, and
ECC parity areas that cannot be written to. Each ECC user area (referred to as main and
spare) must be written within one partial-page program so that the NAND device can
calculate the proper ECC parity. The number of partial-page programs within a page
cannot exceed four.
