ST Microelectronics M25P20VMN6 2Mbits (256K x 8) Serial Flash Memory with 25Mhz SPI Bus Interface.It is designed with an advanced write protection mechanisms and accessed by high speed SPI-compatible bus. Single byte up to 256 bytes can be program at a time using page program instruction. The memory is organized as 4 sectors with each containing 256 pages. And each page is 256 bytes wide. Thus the whole memory can be viewed as 1024 pages or 262,144 bytes.
