20080239784 | HIGH DENSITY PLANAR MAGNETIC DOMAIN WALL MEMORY APPARATUS - A magnetic domain wall memory apparatus with write/read capability includes a plurality of coplanar shift register structures each comprising an elongated track formed from a ferromagnetic material having a plurality of magnetic domains therein, the shift register structures further having a plurality of discontinuities therein to facilitate domain wall location; a magnetic read element associated with each of the shift register structures; and a magnetic write element associated with each of the shift register structures, the magnetic write element further comprising a single write wire having a longitudinal axis substantially orthogonal to a longitudinal axis of each of the coplanar shift register structures. | 10-02-2008 |
20090168485 | PIPE LATCH DEVICE OF SEMICONDUCTOR MEMORY DEVICE - A pipe latch device includes an output controller for outputting first and second output control signal groups based on a DLL clock signal and a driving signal; an input controller for generating an input control signal group; and a pipe latch unit for latching data on a data line when a corresponding input control signal is activated, and outputting latched data when a corresponding output control signal is activated, wherein the output controller includes a plurality of shifters, each for delaying an input data signal by half clock and one clock to output a first and second output signals in synchronization with the DLL clock signal and the driving signal; and a plurality of output control signal drivers for outputting the first and second output control signal groups based on the first and second output signals. | 07-02-2009 |
20100290263 | CIRCUIT AND METHOD FOR CONTROLLING READ CYCLE - A circuit for controlling the read cycle includes plurality of shift stages configured to sequentially shift read signals; and an activating unit configured to activate a read cycle signal which represents a read cycle, by performing logical operation for output signals of the plurality of the shift stages, wherein the plurality of the shift stages are configured to sequentially shift the read signals for a period corresponding to burst setting information. | 11-18-2010 |
20110267868 | SHIFT REGISTER MEMORY DEVICE, SHIFT REGISTER, AND DATA STORAGE METHOD - According to one embodiment, a shift register memory device includes a shift register, a program/read element, and a rotating force application unit. The shift register includes a plurality of rotors arranged along one direction and provided with a uniaxial anisotropy. Each of the plurality of rotors has a characteristic direction rotatable around a rotational axis extending in the one direction. The program/read element is configured to program data to the shift register by causing the characteristic direction of one of the rotors to match one selected from two directions conforming to the uniaxial anisotropy and configured to read the data by detecting the characteristic direction. The rotating force application unit is configured to apply a rotating force to the shift register to urge the characteristic direction to rotate. The plurality of rotors are organized into a plurality of pairs of every two mutually adjacent rotors. A first force acts to urge the characteristic directions to be opposingly parallel for two of the rotors belonging to the same pair. A second force acts to urge the characteristic directions to be opposingly parallel for two mutually adjacent rotors belonging to mutually adjacent pairs. | 11-03-2011 |
