Corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP) are characterized by their unique clinical features and neuronal pathology. Although astrocytic plaques and tufts of abnormal fibers have been suggested to be specific histopathologic markers, recent studies have revealed significant clinicopathologic overlap between CBD and PSP.

A 16 Gb 16-level-cell (16LC) NAND flash memory using 70 nm design rule has been developed . This 16LC NAND flash memory can store 4 bits in a cell which enabled double bit density comparing to 4-level-cell (4LC) NAND flash, and quadruple bit density comparing to single-bit (SLC) NAND flash memory with the same design rule. New programming method suppresses(More)
Traumatic knee dislocations are severe injuries that involve damage to the anterior cruciate ligament, the posterior cruciate ligament, and the lateral or medial ligamentous structures. There are no established methods of treatment. The objective of the current study was to report the clinical outcome of a two-stage autologous reconstruction on nine knees(More)
Development of a compact video encoding system that conforms to the MPEG2 standard is important for real-time visual communication. Motion estimation (ME) to find the best motion vector (MV) representing a spacial displacement for motion compensation (MC) has impact on image quality. Previous ME LSIs for MPEG2 are not suitable for compact, low-cost video(More)
A case of adult-onset adrenoleukodystrophy involving predominantly the cerebellum and brain stem is described. The patient was a 30-year-old man with no family history of adrenoleukodystrophy. His neurological symptoms were progessive cerebellar ataxia and spastic paraparesis. CT showed atrophy of the cerebellum and brain stem. MRI disclosed lesions,(More)
Today NAND Flash memory is used for data and code storage in digital cameras, USB devices, cell phones, camcorders, and solid-state disk drives. Figure 13.6.1 shows the memory-density trend since 2003. To satisfy the market demand for lower cost per bit and higher density nonvolatile memory, in addition to technology scaling, 2b/cell MLC technology was(More)
An 8-Gb multi-level NAND Flash memory with 4-level programmed cells has been developed successfully. The cost-effective small chip has been fabricated in 70-nm CMOS technology. To decrease the chip size, a one-sided pad arrangement with compacted core architecture and a block address expansion scheme without block redundancy replacement have been(More)
A 64 Gb MLC NAND flash memory in 19 nm CMOS technology has been developed. By adopting one-sided all bit line (ABL) architecture, the single cell array configuration, bit line bias acceleration (BLBA) and BC states first program algorithm, the smallest 64 Gb die size in 2 bit/cell is achieved with high performance of 15 MB/s program throughput. Program(More)
An embedded DRAM using a standard NAND flash memory process has been demonstrated for the first time. This embedded DRAM without extra costly manufacturing process realizes 2.4 mm<sup>2</sup> /Mb macro density and provides large-capacity on-chip page buffers and data caches for NAND flash memories to enhance their performances. A 32 KB DRAM buffer macro(More)
