🔋 Introduction to Spin Transfer Torque Magnetic Random Access Memory

Spin Transfer Torque Magnetic Random Access Memory (STT-MRAM) is a type of memory technology that uses spin transfer torque to switch the magnetization of a ferromagnetic film. This technology has gained significant attention in recent years due to its potential to replace traditional DRAM and SRAM. STT-MRAM offers several advantages, including low power consumption, high speed, and high density. According to IBM, STT-MRAM can achieve speeds of up to 1 ns and densities of up to 1 Gb per chip. As a result, STT-MRAM is being explored for use in a variety of applications, including artificial intelligence, IoT, and cloud computing.

💻 Principles of Spin Transfer Torque Magnetic Random Access Memory

The principles of STT-MRAM are based on the spin transfer torque effect, which occurs when a spin-polarized current flows through a ferromagnetic film. This effect causes the magnetization of the film to switch, allowing for the storage of data. The spin transfer torque effect is a result of the interaction between the spin-polarized current and the magnetic field of the ferromagnetic film. As explained by Stanford University researchers, the spin transfer torque effect can be enhanced by using materials with high spin polarization and low damping constants. STT-MRAM cells typically consist of a magnetic tunnel junction (MTJ) and a spin transfer torque writing circuit. The MTJ consists of two ferromagnetic films separated by a tunnel barrier, while the writing circuit provides the spin-polarized current needed to switch the magnetization of the ferromagnetic films.
