    Abstract: A memory device in which data can be retained for a long time is provided. The memory device includes a memory element and a transistor which functions as a switching element for controlling supply, storage, and release of electrical charge in the memory element. The transistor includes a second gate electrode for controlling the threshold voltage in addition to a normal gate electrode. Further, the off-state current of the transistor is extremely low because an active layer thereof includes an oxide semiconductor. In the memory device, data is stored not by injection of electrical charge to a floating gate surrounded by an insulating film at high voltage but by control of the amount of electrical charge of the memory element through the transistor whose off-state current is extremely low.

    Abstract: A NAND Flash based content addressable memory (CAM) is used for a key-value addressed storage drive. The device can use a standard transport protocol such as PCI-E, SAS, SATA, eMMC, SCSI, and so on. A host writes a key-value pair to the drive, where the drive writes the keys along bit lines of a CAM NAND portion of the drive and stores the value in the drive. The drive then maintains a table linking the keys to location of the value. In a read process, the host provides a key to drive, which then broadcasts down the word lines of blocks storing the keys. Based on any matching bit lines, the tables can then be used to retrieve and supply the corresponding data to the host.
