Working Principle

The S29JL064J55TFI003 device is a ferroelectric random access memory (FRAM), which combines the advantages of both random access memory (RAM) and nonvolatile memory (NVM).FRAM combines the benefits of RAM, which includes fast read/write speeds, low power consumption, and low cost, with those of NVM, which includes high data retention and reliability. Data stored in the ferroelectric layer is stored electrically and is retained when power is removed. The stored data is accessed using capacitors, which act as a condenser to store data bits. An electric pulse is used to set the state of the capacitors and is sent to the capacitors for switching between two states. The two states, known as the “1” and “0” states, allow for data to be read or written.S29JL064J55TFI003 uses a simple yet robust design for its ferroelectric cell array. It consists of two field-effect transistors, a FRAM and access device, and the ferroelectric capacitor. When the ferroelectric capacitor and the access device are energized, the capacitor acts as a condenser and stores the data bits. The FRAM device is then used to switch between the “1” and “0” states. The ferroelectric capacitor and access device are reset using a pulse that is sent when the memory cycle is complete.

The S29JL064J55TFI003 memory also offers various power-saving features to reduce power consumption even further. The low-power mode reduces current consumption by providing the system with a POR(power-on reset) and chip interrupt (mouse) signals, while the no-power mode reduces current consumption even further.

The S29JL064J55TFI003 memory is an ideal choice for high-density memory applications requiring low power consumption, low-cost, high-reliability, and fast read/write speed. Its ferroelectric technology enhances data integrity, making it suitable for applications where data integrity is of utmost importance.
