The AT49F001AT-55TI belongs to the nonvolatile memory family. It is an electrically erasable and programmable read only memory (EEPROM) chip which means it can store data without the need for a continuous power supply. It can store up to 1 megabit of data, which is equal to 128 KiloBytes (KBytes). This chip is also known as Single-Time Programmable (STP) because it can retain data even after its power supply is cut off.

The AT49F001AT-55TI memory chip is widely used in the consumer electronics and industrial control automation fields. It can be found in devices such as in medical equipment, telecommunication systems, automotive systems, consumer electronics, and industrial control systems. It is commonly used for protection, authentication, security, and code storage in all kinds of applications.

The AT49F001AT-55TI can operate at 3.3V or 5V voltage supply and offers fast access times of 40 MHz with a 5V input and 20 MHz with a 3.3V input. It also offers high endurance of up to 100K write cycles and long data retention of up to 10 years.

The working principle of the AT49F001AT-55TI is based on stored charges in floating gate transistors. Each transistor has three terminals - the source, the drain, and the gate, which is located between them. When a voltage is applied between the source and the gate, a capacitor is formed and electrons will accumulate in the floating gate, making it conductive and storing a charge in the gate. When the voltage is reversed, the charge is removed and the transistor can no longer conduct.

The AT49F001AT-55TI chip contains a number of transistors with floating gates, thus allowing it to store a large amount of data. The AT49F001AT-55TI has an array of up to 32,768 memory cells, each of which can hold either a 0 or 1, and each cell corresponds to a single bit of data. To read and write data, the chip uses a two-phase process, where in the first phase, a series of transistors are addressed in order to select one bit, and in the second phase, the data is either read from or written to that memory cell. By sequencing through this two-phase process, the chip can read and write data to its memory cells.

The AT49F001AT-55TI is a reliable nonvolatile memory chip that is used in many applications. It is capable of storing large amounts of data, has fast access time and high endurance, and offers a reliable means of data storage. In addition, it is highly compatible with both 3.3V and 5V voltage supplies.
