As the atom gets displaced through an energy barrier in the crystal, it causes a current pulse and the internal circuit sense this spike and sets the memory. The central atom moves in the direction of the applied electric field. The atom positions at the top and bottom of the crystals are said to be stable. While reversing the field causes the atom to move in the opposite direction. Whenever an electric field is applied across the face of the crystal, the atom moves in the direction of the given field. 2 – Structure of Ferroelectric Crystalįerroelectric Crystal is made up of ionic crystals and the structure is cubic with Barium ions at the cube corners, oxygen ions at the face centers and Titanium ion at the body center. To know the working principle of Ferro electric Random Access Memory (FRAM), let us understand about Ferro electric Crystal as shown in the figure. How does Ferroelectric Random Access Memory (FRAM) work Hence, Ferroelectric Random Access Memory is non-volatile. This is termed as remnant polarization which is non-linear polarization. If the external field is removed from FRAM, it will remain polarized. The memory cell consists of a Ferro electric capacitor and a MOS transistor and Data is read by applying an electric field to the capacitor. 1 – Introduction to Ferroelectric Random Access Memory (FRAM) FRAM is unaffected by magnetic fields as there is no ferrous material (iron) in the chip.įig. The data stored in FRAM memories is not lost even when the power is removed. This type of memory consumes less power, is many times faster and provides more than 1 trillion (1013) read/write cycles. The Ferroelectric Random Access Memory, known as FeRAM or FRAM is an ideal, Non- Volatile memory that provides the benefits of both Dynamic RAM and ROM.
