S99FL164KI000 is a type of memory, which belongs to the Flash Memory, in particular, Serial Access Flash Memory. It is used primarily for digital consumer applications that require both cost-effective and reliable non-volatile data storage, as well as low power operation in order to prolong battery life for such applications as PDAs, cell phones, digital cameras and digital music players.

S99FL164KI000 is a 2M-bit (256K x 8) Serially Accessible Electrically Erasable Programmable Read Only Memory (EEPROM). It is a 3V device, providing high flexibility and access time, and is the complete solution to support a wide range of consumer electronic products which require a combination of features such as high data throughput, power conservation, low power operation, endurance and enhanced date security.

The S99FL164KI000 Flash Memory is a standard 16-bit Flash Memory die with a Serial Peripheral Interface (SPI) and Security Options to meet the non-volatile memory requirements of digital consumer applications. This Flash Memory is easily readable, programmable and erasable through the SPI, providing superior ease-of-use for the consumer electronics system designer. The S99FL164KI000 runs at 4-MHz SPI clock frequency, allowing fast write and read operations for data intensive applications.

In terms of its application field, the usage of S99FL164KI000 Flash Memory is mainly in digital consumer applications, mainly those that use non-volatile data storage. Examples of such applications include PDAs, cell phones, digital cameras and digital music players.

In terms of its working principle, the S99FL164KI000 uses a 5V or 3V power supply; a Serial Peripheral Interface (SPI) to transfer data to and from the Flash Memory; a sustained operation frequency of 4MHz; Program and Erase operations for reading and writing data to the Flash Memory; and a Security Options which allows for the data stored in the Flash Memory to be securely erased and read.

In order to write data to the Flash Memory, a write enable (WE) is asserted, followed by the write enable status latch bit being set (WEL) and then a write sequence being initiated. Once the data is written to the Flash Memory, the data is retained in the absence of power. The Program and Erase operations can only be initiated when the device is in the ready state.

To read data from the Flash Memory, the Chip Select (CS) is asserted followed by an instruction command being sent. The data is then sent back to the device and read. Data can also be read using a Quad Command Data Protocol (QCDP) which requires applying 4 clock cycles instead of the usual 8 clock cycles. In either case, the data stored in the Flash Memory remains secure as it is not accessible to unauthorized users.

In conclusion, S99FL164KI000 Flash Memory is a type of memory that belongs to the Flash Memory family and is mainly used for non-volatile data storage in digital consumer applications such as PDAs, cell phones, digital cameras and digital music players. Its working principle involves asserting the write enable (WE), setting the write enable status latch bit (WEL) and initiating a write sequence. In order to read data from the Flash Memory, it requires asserting the Chip Select (CS) and sending an instruction command, with additional protocols available in order to access the data stored in the Flash Memory securely.
