of ECC calculation methods. The ECC calculation method using Hamming codes can be used for
NAND Flash memory of SLC (Single Level Cell) type and is capable of detecting a single-bit
error for every 256 bytes. The ECC calculation method using Reed-Solomon codes can be used
for NAND Flash memory of MLC (Multi Level Cell) type and is capable of detecting four error
addresses for every 518 bytes.
are shared between the two channels. Only the operation of channel 0 is explained here.
The NAND Flash Controller (NDFC) is provided with dedicated pins for connecting with
The NDFC also has an ECC calculation function for error correction and supports two types
Although the NDFC has two channels (channel 0, channel 1), all pins except for Chip Enable
The NDFC has the following features:
Note 1: The
Note 2: The two channels cannot be accessed simultaneously. It is necessary to switch between the two channels.
1) Controls the NAND Flash memory interface through registers.
2) Supports 8-bit and 16-bit NAND Flash memory devices.
3) Supports page sizes of 512 bytes and 2048 bytes.
4) Supports large-capacity block sizes over 256 Kbytes.
