Working Principles

The 24VL014H/SN utilizes Electrically Erasable Programmable Read-Only Memory (EEPROM) technology. It stores data by trapping electric charges within a floating gate structure. These charges can be selectively removed or added using electrical signals, allowing data to be erased and reprogrammed as needed.

During read operations, the stored charges are sensed and converted into digital data. Write operations involve applying specific voltage levels to the memory cells, modifying the charge distribution and thus altering the stored data.
