NEC Corporation and Tohoku University announced today the development of the world’s first content addressable memory (CAM) that both maintains the same high operation speed and non-volatile operation as existing circuits when processing and storing data on a circuit while power is off.
NEC’s new CAM is a part of spintronics logic integrated circuit technologies that utilize the negative properties of electrons together with the spin magnetic moment. The new CAM utilizes the vertical magnetization of vertical domain wall elements in reaction to magnetic substances in order to enable data that is processing within the CAM to be stored on a circuit without using power. This contrasts to conventional technologies that required data to be stored within memory. As a result, data can be saved on circuits even when power is cut from the CAM.
