Working Principles

The AT27C010L-90TI operates based on the principle of electrical charge trapping. During programming, a high voltage is applied to the specific memory cells, causing electrons to become trapped in the floating gate. This trapped charge determines the logic state of each memory cell, allowing for the storage of binary data.

During read operations, the stored charge is detected, and the corresponding data is retrieved. The write enable pin (WE) and output enable pin (OE) control the writing and reading processes, respectively.
