The unnecessarily increase of the information amount of subscriber information retained by a local subscriber information management device is prevented even if the number of subscribers increases, so that the limit of the number of subscribers is extended to support the increasing number of subscribers without increasing the capacity of subscriber information retaining means in the local station (local subscriber information management device). Based on information contained in subscriber management information 211, 221 including information representing each mobile terminal 310, 320 acquired by local stations 210, 220 of a mobile communication system 100 and subscriber information corresponding to each mobile terminal 310, 320, the relevant subscriber management information 211, 221 are selected and processed to be prevented from being retained after call control is performed according to the acquired subscriber management information.
Abstract:
Provided is a method and an apparatus for reading barcode information; the method and apparatus being able to read barcode information correctly without being influenced by the environmental conditions at the time of reading the barcode information. When a reading method according to a prescribed rule could not read a character, each element width is judged again to be either thin or thick according to structural characteristics of characters to convert again an element width matrix into a bit pattern, and then a character corresponding to the bit pattern as a result of the re-conversion is determined.

The beginning of charging a first word line located between the selected word line and a source line to a first intermediate voltage for writing is followed by the beginning of charging a second word line located between the selected word line and a bit line contact to a second intermediate voltage for writing.
Abstract:
A non-volatile semiconductor device has a memory cell array having electrically erasable programmable non-volatile memory cells, reprogramming and retrieval circuits that temporarily store data to be programmed in the memory cell array and sense data retrieved from the memory cell array. Each reprogramming and retrieval circuit has first and second latches that are selectively connected to the memory cell array and transfer data. A controller controls the reprogramming and retrieval circuits on a data-reprogramming operation to and a data-retrieval operation from the memory cell array. Each reprogramming and retrieval circuit has a multilevel logical operation mode and a caching operation mode. In the multilevel logical operation mode, re-programming and retrieval of upper and lower bits of two-bit four-level data is performed using the first and the second latches to store the two-bit four-level data in one of the memory cells in a predetermined threshold level range. In the caching operation mode, data transfer between one of the memory cells selected in accordance with a first address and the first latch is performed while data transfer is performed between the second latch and input/output terminals in accordance with a second address with respect to one-bit two-level data to be stored in one of the memory cells.
