Working Principles

The S29GL064N90FFI020 flash memory operates based on the principles of floating gate transistors. It uses electrically erasable programmable read-only memory (EEPROM) technology, which allows for both erasing and programming of data. The memory cells store information by trapping electrons in the floating gate, altering the transistor's threshold voltage.

During read operations, the stored charge is measured, determining whether the cell contains a logical 0 or 1. Write operations involve applying higher voltages to remove or inject electrons into the floating gate, modifying the threshold voltage accordingly.
