Working Principles

IS25LQ032B-JBLE-TR utilizes the Serial Peripheral Interface (SPI) protocol for communication with the host device. It stores data in memory cells using floating-gate transistors. The presence or absence of an electric charge on the floating gate determines the stored data value (0 or 1). Reading involves sensing the charge level, while writing and erasing operations modify the charge level on the floating gate.
