A stepped surface relief structure positioned on a substrate is configured to reflect narrow-band light wavelengths and is further configured such that the substrate can be incorporated into at least one of a thread, a fiber or a flake. The debug apparatus includes a processor for controlling the chip under test via a bridge device. When the data processing device is in a hypervisor mode, a second TLB is accessed in response to the request to access the page tables. The method and system for enhancing resolution of a magnetic resonance image is highly beneficial for a MRI practitioner by substantially improving image quality, thus facilitating diagnostic methods such as texture analysis and disease specific tissue segmentation. The circuit includes a plurality of boosted voltage generators configured to generate a boosted voltage having different current driving capabilities to activate the non-edge sub-arrays and the edge sub-arrays and to supply the boosted voltage to the memory cell array. A repair can thus be carried out on the unhoused semiconductor memory and on the housed semiconductor memory.
