20140071728 | READ-DISTURBANCE-FREE NONVOLATILE CONTENT ADDRESSABLE MEMORY (CAM) - Voltage controlled magnetoelectric tunnel junction (MEJ) based content addressable memory is described which provides efficient high speed switching of MEJs toward eliminating any read disturbance of written data. Each cell of said CAM having two MEJs and transistor circuitry for performing a write at voltages of a first polarity, and reads at voltages of a second polarity. If the data searched does not equal the data written in the CAM, then the match line state is changed. | 2014-03-13 |
20140071729 | STACKED SEMICONDUCTOR DEVICES INCLUDING A MASTER DEVICE - A stack that includes non-volatile memory devices is disclosed. One of the non-volatile memory devices in the stack is a master device, and the remaining memory device or devices is a slave device(s). | 2014-03-13 |
