Abstract:
A rotor for use in an induction motor includes a main body installed to be rotatable by having a gap inside a stator, providing a flow path of magnetic fluxes produced from the coil, and including a plurality of conductors formed on an edge region of the main body; a pair of barriers formed to pass through the main body in a manner to have a semi-spherical shape from a sectional view, base lines of the semi-spherical shape being disposed to face each other; and a plurality of permanent magnets disposed inside the individual barriers. Therefore, the permanent magnets can be easily affixed to the inner side of the individual barriers, and the loss of the magnetic fluxes is minimized, thereby improving the efficiency of the rotor.
Abstract:
A non-volatile memory device has the pages of a certain memory block reallocated to other blocks in order to increase decrease disturb and increase reliability. Each of the reallocation blocks that contain the reallocated pages from the desired memory block are coupled to a wordline driver. These wordline drivers have a subset of the global wordlines as inputs. The desired wordline driver is selected by an appropriate select signal from a block decoder and an indication on an appropriate global wordline. This causes the wordline driver to generate a local wordline to the desired block with the reallocated page to be accessed.
