Working Principles

The M27C160-100B1 utilizes a technology called floating-gate MOS (metal-oxide-semiconductor) to store data. When programming the chip, electrical charges are trapped in the floating gate, representing the desired data. These charges remain trapped even when power is removed, ensuring data retention.

During read operations, the chip applies appropriate voltages to the memory cells and reads the stored charges. The output pins provide the corresponding data based on the addressed memory location.
