  • Patent number: 8729615
    Abstract: A semiconductor memory device has a memory cell region and a peripheral region. The device includes low voltage transistors at the peripheral region having gate insulation films with different thicknesses. For example, a gate insulation film of a low voltage transistor used in an input/output circuit of the memory device may be thinner than the gate insulation film of a low voltage transistor used in a core circuit for the memory device. Since low voltage transistors used at an input/output circuit are formed to be different from low voltage transistors used at a core circuit or a high voltage pump circuit, high speed operation and low power consumption characteristics of a non-volatile memory device may be.

  • Publication number: 20130143490
    Abstract: A data transmitting and receiving apparatus includes a coil configured to transmit and receive data through inductive coupling, where a voltage drop across the coil constitutes a sensing signal. The apparatus further includes an input unit configured to generate transmission data and a replica signal in accordance with an input data signal, the transmission data being supplied to the coil. The apparatus still further includes a replica unit configured to generate a compensation signal in accordance with the replica signal, and an output unit configured to extract reception data from the sensing signal using the compensation signal.

  • Patent number: 8441869
    Abstract: Some embodiments of the present invention provide data storage systems including a plurality of memories and a control circuit coupled to the plurality of memories by a common channel. The control circuit is configured to sequentially transfer respective units of data to respective memories within each of a plurality of predetermined groups of the plurality of memories over the common channel and to transition from transferring units of data to a first one of the groups to transferring units of data to a second one of the groups based on an attribute of the units of data. The attribute may be related to a programming time associated with a unit of data. For example, the attribute may include a bit significance of the unit of data.
