Description
NAND01G-B2B and NAND02G-B2C flash 2112-byte/1056-word page is a family of nonvolatile flash memories that uses NAND cell technology. The devices range from 1 Gbit to 2 Gbits and operate with either a 1.8 V or 3 V voltage supply. The size of a page is either 2112 bytes (2048 + 64 spare) or 1056 words (1024 + 32 spare) depending on whether the device has a x8 or x16 bus width.
