2.6 Memory Array Organization

The Flex-MuxOneNAND architecture integrates several memory areas on a single chip.

2.6.1 Internal (NAND Array) Memory Organization

The on-chip internal memory is a convertible(SLC and MLC) NAND array used for data storage and code. The internal memory is divided into a main area and a spare area.

Main Area

The main area is the primary memory array. A block incorporates 64pages(SLC) or 128pages(MLC). A main page size is 4KB and a main page is comprised of 8 sectors each size of which is 512Byte.

Spare Area

The spare area is used for invalid block information and ECC storage. Spare area internal memory is associated with corresponding main area memory. A spare page size is 128B and a spare page is comprised of 8 sectors each size of which is 16Byte.
