Crocus developed NAND-like MRAM based technology called Magnetic Logic Unit (MLU)

Crocus developed a new technology called Magnetic-Logic-Unit (MLU), which is an evolution of their Thermally Assisted Switching (TAS) technology. MLU allows for practical implementation of advanced logic and memory capabilities - which will enable new applications in high density data storage, secure commerce and communications, high performance network processing and high temperature automotive and industrial markets.

Crocus' MLU provides stability to the stored data in normal operation. The MLU's reference leayer can be configured in three ways:

  • With Fixed magnetization to implement a traditional NOR function
  • With floating magnetization to implement a NAND function
  • With driven magnetization to implement an XOR function, which ultra-secure compare and encrypt function.

The most exciting application is the floating magnetization - which implements NAND magnetic memory - and high density applications. MLU NAND will be two to four times denser than normal MRAM and enable full random access.

The XOR configuration is anti-tamper MRAM with applications in security (SIM cards, NFC, smart cards, etc.).

According to Crocus, MLU could potentially replace SRAM, DRAM, NAND, NOR and OTP. And all those capabilities are manufactured using the same simple wafter process - with different design architecture.

MLU volume production will begin at Crocus' 130nm foundry partner (Tower Jazz semiconductor) and at their upcoming Russian fab for 90nm, 65nm, 45nm (and even smaller lithography)
