On the passing CEATEC exhibition in Japan TDK company demonstrated a prototype chip magnetoresistive random access memory with spin transfer - STT-MRAM. According to the level of performance comparable to this memory SRAM and DRAM, but the STT-MRAM differs non-volatility and can store the recorded data for long periods.
Various embodiments of the magnetoresistive memory are developed for a long time. TDK focuses on technology spin transfer - when data is written under the influence of an electric current of spin-polarized, there is a change in the orientation of the magnetic field. The exhibition displays 200-mm plates with crystals STT-MRAM, the density of which is 8 Mbps, as well as of packaged chip.
Unfortunately, TDK will not soon begin mass production of STT-MRAM memory - according to various estimates, the maturation of the technology will go from five to ten years.
Incidentally, TDK is not the only company that develops technology STT-MRAM. Its main competitor in this area is Everspin Technologies, which already leads the supply of relevant chips in limited quantities. Everspin memory is used, in particular, as a cache SSDs Buffalo Memory. Related Products :
