Serial Flash Memory is a type of non-volatile memory that stores digital information in a series of memory cells, typically organized in an array of rows and columns. Unlike RAM (Random Access Memory), which loses its data when power is removed, flash memory retains data even when power is turned off. Serial flash memory is characterized by its serial interface, meaning data is accessed and written one bit at a time through a single data line, as opposed to parallel flash memory that transfers multiple bits simultaneously through multiple lines.

Description
The GD25Q16 (16M-bit) Serial flash supports the standard Serial Peripheral Interface (SPI), and the Dual/Quad SPI: Serial Clock, Chip Select, Serial Data I/O0 (SI), I/O1 (SO), I/O2 (WP#), I/O3 (HOLD#). The Dual I/O data is transferred with speed of 266Mbit/s, and the Quad I/O data is transferred with speed of 532Mbit/s.
