SUMMARY DESCRIPTION

The NAND Flash 528 Byte/ 264 Word Page is a family of non-volatile Flash memories that uses

the Single Level Cell (SLC) NAND cell technology. It is referred to as the Small Page family. The devices range from 128Mbits to 1Gbit and operate with either a 1.8V or 3V voltage supply. The size of a Page is either 528 Bytes (512 + 16 spare) or 264 Words (256 + 8 spare) depending on whether the device has a x8 or x16 bus width.
