A flash memory device according to the present invention includes a semiconductor fin including a top surface and a side surface originated from different crystal planes. The flash memory device comprises: insulating layers having different thicknesses formed on a side surface and a top surface of the semiconductor fin, a storage electrode, a gate insulating layer and a control gate electrode sequentially formed on the insulating layers. A thin insulating layer enables charges to be injected or emitted through it, and a thick insulating layer increases a coupling ratio. Accordingly, it is possible to increase an efficiency of a programming or an erase operation of a flash memory device.

The present invention provides a storage system for storing variable sized objects. The storage system is preferably a transaction-based system that uses variable sized objects to store data. The storage system is preferably implemented using arrays disks that are arranged in ranks. Each rank includes multiple stripes. Each stripe may be read and written as a convenient unit for maximum performance. A rank manager is able to dynamically configure the ranks to adjust for failed and added disks by selectively shortening and lengthening the stripes. The storage system may include a stripe space table that contains entries describing the amount of space used in each stripe. An object map provides entries for each object in the storage system describing the location (e.g., rank, stripe and offset values), the length and version of the object. A volume index translates regions of logical storage into object identifiers. The storage system may implement various types of formats such as I-node, binary tree and extendible hashing formats.

A semiconductor device includes a plurality of nonvolatile memory cells (1). Each of the nonvolatile memory cells comprises a MOS type first transistor section (3) used for information storage, and a MOS type second transistor section (4) which selects the first transistor section. The second transistor section has a bit line electrode (16) connected to a bit line, and a control gate electrode (18) connected to a control gate control line. The first transistor section has a source line electrode (10) connected to a source line, a memory gate electrode (14) connected to a memory gate control line, and a charge storage region (11) disposed directly below the memory gate electrode. A gate withstand voltage of the second transistor section is lower than that of the first transistor section. Assuming that the thickness of a gate insulating film of the second transistor section is defined as tc and the thickness of a gate insulating film of the first transistor section is defined as tm, they have a relationship of tc<tm.

Each pixel cell (12) of an image sensor (10) is made of a 4-Tr structure, in which only one Tr for resetting a column (X) is so added to an ordinary 3-Tr APS as to reset only an arbitrary pixel selectively, thereby to confine the pixel size. When a pixel signal is to be read, the period, for which the pixel signals composing an ordinary image of one frame are read, is finely divided so that the pixel signals of the pixels receiving an ID light for the period are read out bit by bit and repeatedly. At this time, for only the column being read, an electric current is fed to a read amplifier in the pixel cell (12) or a variable gain amplifier in an output unit (14), thereby to suppress the power consumption. As a result, a lower power consumption and a higher pixel formation can be attained in an image pickup device for picking up an image and for acquiring the ID information of a light beacon existing in the image pickup range.

A non-volatile memory has its cells' thresholds programmed within any one of a first set of voltage bands partitioned by a first set of reference thresholds across a threshold window. The cells are read at a higher resolution relative to a second set of reference thresholds so as to provide additional soft bits for error correction. The reference thresholds of the second set are set up to be non-uniformly distributed on the threshold window so as to provide higher resolution at designated regions. At the same time they are conducive to be read in groups for soft bits to be read bit-by-bit systematically with a simple algorithm and read circuit and using a minimum of data latches. This is accomplished by relaxing the requirement that the first set of reference threshold is a subset of the second set and that the resulting soft bits are symmetrically distributed about the hard bits.
